However one of the big problem was it was difficult to moderate (for the ones that were moderated). And since it is/was outside of BB, anyone could theorically disguise as someone else or use a totally different name, so we couldn't sanction in game.
Hahaha I could remember going in using someone else's username as my name to prank a friend.
But yea, would an internal chat be hard to make I wonder? Why did they have to use an external chat system instead of one which made you post with your own account that you are currently logged into?
In my previous country we used to have people logging in to watch NT/U21 games in the past, and you occasionally you'd see your league opponent logged into the chat as well, then the both of you can chat. Made things more interesting back then.
