I haven't seen it mentioned but SPAM is also a post which is "over the top" off topic...this can also be large photos which are not on topic or not necessary to get the message across.

In my book - SPAM is one of those things that are not necessarily cast in stone, a moderator has to use his/her judgment as to whether it is - or isn't....it also depends on what forum it is in...

I second the dr's interest in including numerous threads on the same subject and the OP doesn't answer questions put forth by others...this is an idea that merits mod discussion....consequently it was just that - that lead to the number of threads made in a day limit..
