If I'm not mistaken there are 3, 7, and 10 day bans on AI including a permanent one. There's a warning system but I haven't seen it used ever. Members should also be notified if something they wrote has led to an infraction. I don't know what it was BF wrote, but it seems to have gotten him banned permanently. I do agree with you, the terminology should be changed, temp bans should read 'user suspended' instead of 'banned user'.
