You are prohibited from using your real name on these forums, either as your username or in posts / PMs you write.

FORUM RULES, IN ADDITION TO THE DISCLAIMER

1. These rules apply to all sections of USPOL, including public and private forums, blogs, and visitor messages.

2. You cannot attack and/or personally insult someone. You cannot bait other forum members; this includes referring to posters by derogatory terms. Please, remain courteous and respectful to all forum members at all times. You agree to take responsibility for reporting such posts when you come across them. Please, use the ignore feature if need be. Any member who intentionally and continually posts inflammatory, extraneous, or off-topic messages with the primary intent of provoking readers into an emotional response, or of otherwise disrupting normal on-topic discussion, may be regarded as a “troll” by staff, and have their account suspended or banned.

3. You cannot harass (sexually or otherwise) other members. This includes malicious, slanderous, or defamatory comments. If you are not sure if something you write is inappropriate or not then don't say it. Err on the side of caution.

4. Copying and Pasting Articles, and Starting New Threads. You cannot simply cut and paste in posts or when starting threads. You MUST provide the identifying information (source, author, date, and URL). You must also offer some original thoughts along with the cut and paste. You may copy and paste an excerpt or series of excerpts from the article. Excerpts really shouldn’t be more then a paragraph or two. Furthermore, if you use images or other copyrighted material in your posts or signature you must have permission of the copyright holder unless you know for a fact that the image is in the public domain. In addition:
a. It must include the identifying information; e.g., where available, the author, the publication, the date, the URL.
b. The member must offer some context, including: How did you hear of this article? What is your opinion? Why is it important to you? Why should it be important to forum readers? The more context you provide, the more you assist others in gauging the excerpted information's significance.
c. You may copy and paste an excerpt or series of excerpts, not the whole thing or even the majority of the whole thing to encourage people to read the entire article.

A violation of any of the above will result in the deletion or closing of the post or thread and could earn you a warning or suspension. If you have any questions concering any of the above please PM a moderator and we will be happy to clarify.

5. You cannot post the same thing in multiple forums. You must not open similar threads about the same or a similar topic. You cannot spam the board or send unsolicited messages to members via PM, email or any other means.

6. Do not post off-topic. You cannot derail a thread with off topic posts.

7. You cannot shout in posts. This includes posting in all CAPS, bold, lIkE tHiS, and extra large font. Posts should also be one color, although you may use an additional color for highlighting ideas you wish to address.

8. You may not alter quotes in a way that misrepresents what was originally said.

9. Multiple accounts are not allowed. If you are found to have more than one account all accounts will be permanently terminated.

10. You cannot have a user name, avatar, signature, or post images that are deliberately offensive. That includes the display of overly explicit or graphic images that may not be suitable for minors.

11. Signatures can not have more than three lines of text, with a font size no larger than "4", and no more than two font colors. Images in signatures cannot be any larger than 800 pixels wide x 200 pixels tall. Animated images are not allowed.

12. You are prohibited from taking any action to disturb the use of the services by others, distribute material that contains viruses, spyware or any other malicious code or harmful programs. This includes interfering with the working of the network, attempts to gain unauthorized access to a service or other computer systems that are part of the site or any other site, by use of the available services.

13. Discussion of moderation actions in public and/or private forums is not permitted. Moderation actions include warnings, suspensions and the editing or deletion of posts. If a member has a concern about a moderation action, he or she is invited to address it with the board staff via Private Message. This rule exists to protect the privacy of all posters with regards to disciplinary action. The moderator team will never publicly discuss the warnings/suspensions of any posters, and we ask that you return the favor, whether about yourself or another poster. Posting about moderation actions in the public forums constitutes a violation. You are free to discuss a moderation action via Private Message with the moderator involved, but you may not harass or abuse the moderators (as already specified in the forum rules). In practical terms, this means that once a moderator tells you his or her decision is final, no further PMs about that moderation action are permitted. If you have a concern about a moderation action, you are free to appeal to a Forum Administrator via Private Message. You may only discuss moderator activities or discussion of moderation with staff member if you chose to private message and are not under any circumstances allowed to use the PM function to forward or promote moderator discussion in regards to specific forum action, amongst other regular members. Administrators do reserve the right to read said PMs and may do so ; if that results in discovery of messaging between posters of such moderator discussion then it will lead to the same violation being received for discussing said moderator actions on the forum. If you receive a message to the effect of having been given moderator information, please report it to a member of staff. Engaging back in that discussion with the original violator will earn you just as stiff a sanction.

14. Do not ignore moderators or administrators. Do not repost something a moderator or administrator has deleted. You cannot have moderators or administrators on your ignore list.

15. Only post in English. Short passages in foreign languages may be acceptable if its use seems helpful for the ongoing discussion and when there is no indication of a potential violation of the forum rules. Always provide a translation into English in such cases. In case of doubt, the incident will be regarded as a violation, no matter of the actual meaning of the foreign language text.

16. The use of words/comments etc. written by other posters, without approval of the poster in your personal signature is not allowed nor are references, by name, to other posters allowed.

17. Please pay attention to announcements by Forum staff that will be found in the "Welcome! / News & Announcements" forum from time to time.

18. Use of "liar", "lies", "lying", etc. Accusing someone of being a "liar" or similar accusations towards other posters will generally be regarded as implying an insult and therewith as a violation of the forum rules. "I question the validity of your statement because...", "That's not the truth" or "you are wrong about that" are sufficient for any decent discussion if you want to disagree with somebody's assertions.

19. Thread opening restriction for new members. In order to control SPAM, new members must have moderator approval to start their own threads.

20. Thread titles must relate to the discussion within. Do not make misleading titles, or titles such as "Guess what..." or "You'll never believe this...". Members need to be able to identify the general gist of the thread via the title. Profanity in thread titles is not permitted.

21. Forum members are instructed to use forum tools and abilities for their intended purposes and no other. If members identify a forum glitch or weakness of any kind that allows you to see or do something you know you shouldn't, please report it. Being aware of any unintended access to the Forum and failing to take appropriate steps to notify staff of said access issues, will create a presumption of seeking to take advantage of the issue, will result in either account suspension, or banishment.

22. Any link to a site that contains graphic content, must contain a warning describing what a person might reasonably expect to view if they click on said link. No graphic pictures are to be posted on the Forum.

23. Threats or advocations of violence toward a public figure, or member of the Forum, will not be tolerated. Conversation about revolution or the like is not prohibited by this rule; directly calling for violence is, eg “It's time to kill every <redacted> that voted for the bill,” is not permitted.

24. Accounts with no posts will be deleted after 30 days. Inactive accounts with low post histories may be deleted after one year.

25. Private forums are something offered to members that decide to contribute directly to this site via donations. These donations help immensely in keeping this site up and running. Private forums are designed to allow the contributing member discuss whatever he/she wants to and to have the power to direct that discussion in whatever way he/she chose. They were not designed nor are they intended for simply talking trash about members that don't have access to the forum. While the targeted members cannot see the forum or the comments, it creates a negative atmosphere that really isn't necessary. If you want to totally rip apart ideas, ideologies, political parties, etc. that is fine. We simply ask that you don't use the private forums as a means to attack other members that aren't privy to such comments. It is difficult enough to have a political discussion forum because the discussion of politics is inherently heated as people are so passionate about their beliefs...the ones that take the time to come to such a site in the first place at least. The idea of private forums is so people of similar political persuasions can discuss whatever they want without fear of being attacked. Nonetheless, we hope that a certain level of maturity would foster itself within such an arena and not simply lend itself to a bashing forum.

Private Forums are governed by all of the above Forum rules. In addition:
  • Private forums that essentially become abandoned homes will be subject to deletion, donation or reorganization. Just like elsewhere in life, clubs sometimes lose their vitality and purpose for a myriad of reasons. If it becomes clear that a private forum has clearly lost its vitality and nobody is going to really use it anymore, owners are advised to consider whether to reuse the forum for something new and productive rather than let them linger or notify the Administration that the forum should be rearranged for other purposes, closed, merged with other compatible private forums, donated to others for new purposes, etc. Do not be concerned that your forum must be a membership and post count race with others to avoid falling under this policy; the question is whether your forum has actual vitality instead of being 'brain dead.'
  • Additionally, private forums may only be owned by subscribed members in the Platinum or Diamond categories.
  • Should the owner of a private forum be banned, quit USPOL or otherwise abandon the forum the PF will be transferred to another owner or closed.
  • Propriety of private forums. Administration staff will determine the desirability of a proposed private forum and enact any conditions upon it to ensure its purpose is productive.
  • Any and all instances of sharing accounts by allowing someone else to log in under their own account so they can see into private forums for which they are otherwise not permitted to access, will be deemed violation of the double account rule and all caught doing so will be permanently banned.
  • Relaying private forum posts and information to other posters who are not members of the particular private forum for any negative or destructive purpose (eg mean-spirited gossip, fueling interpersonal disputes, etc), is not permitted, and will constitute a violation of the Forum rules.
  • For purposes of monitoring USPOL Terms of Service Administrative staff (not Moderators) will have access to Private Forums.
  • All Private Forums must have at least one active Administrator as a member for purposes of handling issues which cannot be addressed through moderation permissions.
  • Discussion of moderation activities is prohibited on the open site and is likewise prohibited in Private Forums.

26. The administrators and moderators reserve the right to edit and/or delete a post,and/or close a thread, and/or delete a thread at any time if of the opinion that the post is too obscene, inappropriate, or the discussion has run its course.

27. 'Back seat moderating' is not allowed. If you take issue with another poster's contribution to the forum, you're welcome to report any posts you think are out of line, but you should not bring it up publicly within the forum.

28. Images in posts (whether embedded or hot linked) must be reasonable in size. 800x800 should be considered a good rule of thumb. Excessively large images make it difficult for users on mobile devices to load pages. If necessary please simply link to very large images using the URL tags. In addition, the following images are not permitted (including, but not limited to pages with images or videos containing):
  • Strategically covered nudity
  • Sheer or see-through clothing
  • Lewd or provocative poses
  • Close-ups of breasts, buttocks, or crotches

29. Any solicitation or communication involving sports betting / gambling / online casinos / bookies and or internet based card or slot machine systems or sites will lead to all said content being physically removed from the site and server, and will lead to any and or all parties involved being permanently removed and banned from the site to the farthest extent possible. This includes any links to any form of bookmaker, casino, any type of game or match or event where money transfers on the outcome or link of any sort to wire act violations and or anything in violation of either the Internet Gambling Regulation, Consumer Protection, and Enforcement Act, Unlawful Internet Gambling Enforcement Act of 2006, or the Federal wire Act. This applies not only to the open forum but all and or any chat rooms, articles, private messages and or private forums. All content that violates this rule will be deleted, without notice.

CONSEQUENCES

Failure to comply with any of the forum rules may result in your posts being edited or deleted and/or your account being temporarily or permanently banned from the forums. U.S. Politics Online uses a warning system that generates an automated Private Message to members when they are in violation of Forum rules. The decision to issue a warning is left to the discretion of the moderator or administrator handling the violation. If a member does not agree with an action taken by a moderator, they can appeal to an administrator after seeking clarification from the moderator who issued the warning/infraction and appealing to them in the first instance. Members MAY NOT harass a moderator or administrator by sending excessive PMs when they are discussing an appeal.

Violations are assigned a point value. Points are valid for 30 days. When a members earns 10 points, their account will be automatically suspended: five (5) days for a first suspension; ten (10) days for a second suspension; and twenty (20) days for a third suspension. If a member incurs an additional 10 points after having served three periods of suspension, then they will be permanently banned from the Forum.

Point values are as follows:
Zero (0) points – Warning
Two (2) points - Minor infraction / Non post infraction (minor) / Off topic posts / spamming
Four (4) points - Academic dishonesty / Baiting / Discussing moderator or administrator actions / Implying an insult / Minor insults / Moderate infraction / Non-post infraction (moderate) / Thread dumping
Six (6) points - Direct insult at another member / major infraction / Non-post infraction (major)
Ten (10) points - Act of criminality, or advocating thereof

The administrators and moderators also bear the right to issue warnings, temporarily suspend or ban posters for continued trolling or other serious misconduct (eg. professional spamming) even if the poster has not yet reached the maximum warning points or suspensions level. Other options if the above consequences do not seem adequate include placing the member in a moderation queue, which means all posts will have to be approved before they are posted to the board.

PRIVACY POLICY

All information obtained by the end user via the registration process is for internal purposes only and will not be sold to or shared with any third parties. However, if the end user participates in illegal activities and a court of proper jurisdiction orders U.S. Politics Online to release certain information about said user then we will act according to the law. Furthermore, no information will be released on threat of a lawsuit, attempted or actual intimidation, or due to any other reason except as notated in the first sentence of this paragraph. Nonetheless, keep in mind that the information we do have is very limited and generally only consists of the IP address a member uses.

  • Why Not Blow Up An Approaching Asteroid?

    150-foot asteroid to zoom near Earth this week | Fox News

    With the reporting of the approaching asteroid, which NASA says will miss up (good), my thoughts turn to the question of why wouldn't you want to launch missiles against an approaching asteroid?

    A big asteroid crashing into the Earth is a bad thing and appears to have caused extinction events previously in Earth's history. Big rock at high speed crashes in one big kinetic impact causing all kinds of destruction, whether it crashes in the ocean or whether it crashes on land. Launching missiles would break the asteroid apart into smaller fragments, each of which would have less kinetic energy and would spread the impacts across a larger region, each being less destructive that the larger version.

    Yet all the experts say that you don’t want to do that; you don’t want to break up a large asteroid into smaller ones. Now why is that?

    HowStuffWorks "Could we really blow up an incoming asteroid with a nuclear bomb?"
    Killer Asteroids -- How will we prevent the destruction of Earth?

    Seems to be that spreading the one large impact across multiple smaller impacts is a win, as each impact has less energy, granted, there would be more impacts.

    Seems to me that breaking up the asteroid increases the number of fragments, each of which would have its own surface area to burn up on its way through that atmosphere, which would reduce the size of the fragments that eventually will crash into the surface. That’d be a win in my book as well.

    Anybody know why there are recommendation that breaking up an incoming asteroid is a bad idea?

      Re: Why Not Blow Up An Approaching Asteroid?

      Well, I suspect if the options were limited to (A) blow up the asteroid with nukes, or (B) just let it hit the planet and kill us all, most people would go with (A). That is to say, I'm not sure people think it's a bad idea so much as they think that it's not as good as alternatives.

      One problem that comes to my mind is that breaking an asteroid up into multiple pieces will make it considerably harder to calculate where those pieces will land. It might be better to have one large impact that we can plan for years (or decades) in advance than several smaller ones that we can't predict or make preparations around. Evacuations, the positioning of emergency supplies, the deployment of relief workers...all of that depends on knowing where the rock is going to hit.
      I.E. From a live's lost standpoint, better to lose the entire state of Pennsylvania, if it's fully evacuated, than to suddenly lose the city of Philadelphia without warning.

      The worst-case scenario would be that the nukes wouldn't break up the asteroid, but just slightly alter it's course/shape so that you still got one huge impact but lost the predictability of it.

      EDIT:
      Of course, all of this is with regard to big, devastating asteroids. If it's just a little 150-footer like the one in the OP then, sure, blow that sucker to kingdom come.

        Re: Why Not Blow Up An Approaching Asteroid?

        I'd like to see a test on a smaller (150-200ft) asteroid, just to make sure we know how to do it properly. How far out does the blast need to be before it doesn't become an EMP? Has anybody ever set off a nuke in space?

          May be better to not know where it's going to land, and I think that there are limitations in our ability to exactly calculate the when and where of an impact. I think that it'll be more like North America as opposed to South America or Europe, and not much more accurate than that. Heck, we couldn't predict the impact point of any of the fallen space stations, the Russian one, or Skylab (I still remember they were worried about the large kiln landing hard)

            If the movies have taught us anything it's that as long as you don't live in one of the popular cities like London, Paris or New York you'll be fine. They never have a film where the world is in peril as an asteroid is about to smash into downtown Ipswich or Newcastle.

            As for doing anything about an asteroid if we have enough time then nudging it a little so it misses is our best option.

              Movies don't teach us jack about anything. Their science is usually all screwed up. I'll bet it's because there is a creative left brain thinker writing the plot.

                I'm no astronomer, but I'd suspect that predicting the impact site of a major asteroid would be much easier than predicting the impact site of space-station debris.
                The debris is, relatively, light-weight and not moving very quickly, so it's trajectory will be heavily impacted by the atmospheric conditions it passes through. A really big asteroid would likely be traveling, much, much faster and have enough mass so that the precise weather it encountered during its brief run through the atmosphere wouldn't make much of a difference.

                By analogy, it's easier to predict the landing site of a baseball than a paper airplane.

                  From what I understand, they didn't even know this one was coming until a short time ago. Since it is not supposed to hit the earth, messing with it is probably not a good idea. The only benefit I can see with shooting something at it is to prove we can hit it.

                      Exactly my point, hence the question why not break it up before it would get here?

                      No one is saying anything about shooting at the one that's goign to miss us. It was just the news topic that made me stop and ask the question.

                        Maybe. What if your choices are:
                        (A) Be shot with a slug, but you can choose where
                        or
                        (B) Take a point-blank blast of bird shot, to a randomly chosen place on your body (but there's a small chance that you'll get shot with the slug anyway).

                          It is an interesting question.

                          First of all if this will miss us and be gone then let it go and not risk it changing trajectory in anyway. Might be tidal influences for a couple days but otherwise we should be fine. Then again 150' wide probably no gravity to speak of.

                          If it was going to hit the earth? Well damn well better start shooting at it. The only downside I see is radioactive pieces hitting the earth instead of just a lump of rock.

                          Probably the one thing is they don't want to admit if they actually placed orbital nukes in space. From what I have read and watched it will sweep closer than the average satellite is to the Earth so I think we are going to lose a handful or more satellites as a result. Maybe communication interruptions as a result.

                            (A) Be shot with a slug, but you can choose where

                            (B) Take a point-blank blast of bird shot, to a randomly chosen place on your body (but there's a small chance that you'll get shot with the slug anyway).

                              From what I understand a nuke detonated at a high altitude acts as an EMP. Would a blast in space not act as an EMP to those on Earth? Does the lack of an atmosphere greatly reduce the impact on Earth or would it make no difference and still act as an EMP and take out sattelites in space? Would conventional explosives be a better option?
