It's considered one of the worst haha
That's why I never want to play it, I assume everyone will hate me because I'm new
Nah, it won't be that bad, just play the game and stay respectful, ignore the trolls and you'll be fine. I've played it a while ago and it's really not that bad, though I've never actively browsed their forums, so I can't say how bad that is. In the time which I have played (which was +- 3 years), I think I've reported about 10 people for abusive behaviour, which is relatively low compared to other online games I tend to play.
tl;dr; Just go and play, it ain't that bad.
