Just to put it into perspective, I took a break for about a year and when I came back few days ago, the chat is such a mess I was quite taken aback. Year ago, people were getting muted, kicked and banned for the kind of shit that happens in the ingame chat today. I'm not a puritan, I don't mind offensive language, but when every single line in a chat is someone calling someone else gay/my old friend/retard/dickhead/asshole/whatever else, better yet in caps lock, it gets a bit tiring. The amount of hate in the chat is staggering.
But from Tenne's post, I guess that the admins prefer to go with the flow rather than do something that would make them unpopular with the community, it was bound to happen.
