I don't know who, actually, there are several unchecked trolls there (four off the top of my head) but one of them I give the benefit of the doubt may not be trolling but just painfully hopeless.
Personally I never got penalized there, one warning point in 10 years and no suspensions. I'd like to think it's because I'm a respectful poster but then again so are many others who have shared ridiculous suspension stories, so who knows, maybe the mods took it easy on me.
For me, I just couldn't take all the incessant deleting, it really takes away from the discourse. While I've been gone they implemented all the popularity changes and now I don't really even like the feel of it anymore.
Watch, next election I'll be back though.
