I've heard through the grapevine that it might have something to do with people from the old boards thinking that it kills the experience of talking/trolling on a forum.
The reason for this, I can only assume, has something to do with people wanting to keep their anonymity, but I say fuck that.
I think it adds to the experience. If you're so concerned with keeping anonymous so much I think you're just a pussy ass troll that can't do it for real because you suck,
but if it's just a matter of not liking cam chats I can understand that, there's no problem with that - it's cool.
TL;DR version: Why?
