This is a pretty nice community. I think we deserve the award for having the fewest ten year olds who all screwed your mom :) Anyway, the spammers and trolls were way worse when we didn't require email verification and when we could still downvote memes. There was even a Trollsmashers group that some of the leaderboard users founded.
Anyway, most of the trolls went away once the big porn spammer was found--and it turned out that it was Mememaker, one of the big leaderboard users. Once he went away, a lot of other leaderboarders left with him. And then Filip, that one annoying guy who was the cause of almost every flame war, kept telling everyone how we were all wrong and how he knew it all along. Aaaaand then he was never seen again. :/
