i will agree that the canadians hands down have the lock on this one.
in the years that i've been on EF, there's always at least 1-2 people at any given time who fill the board with either their half naked pics, threads like "I'm eating an apple" that blow up to 100+ posts(half of which are made by the thread author), or threads with topics that are obviously intended to lure males in - e.g. "I'm in the mood for a big..."
But another guaranteed fact is that the attention whores/board whores never last longer than a few months. Eventually they burn out and wither away into nothingness, never to be heard from again. And then they are replaced by someone else.
