Hey there, welcome to AnxS
Sad fact is that the more people means that there's more chance of assholes appearing. Seen it on many places, not just SAS. I don't go there much anymore, for a similar reason.
Smaller community here...but yeah I like it. There's not as much crap that goes on here. Probably due to our smaller size.
Sadly, that smaller size has not dissuaded the spammers though.
