Who the f*** are you?
Anyway, I guess I'll chip in... The ban isn't a "joke" at all. The people who run this place have two relevant responsibilities here: (1) protecting the interests and reputation of the forum, (2) protecting our users. The first one is self-explanatory - I'm sure I don't need to explain (at least, not to anyone who isn't being contrary just for the sake of it) why it isn't good for the forum to have a hooligan-element associated with it. As for the second, one thing I'd like to bring up is the fact that we have a ticket exchange system on here which the user in question has used in the past to purchase tickets from other users - the fact that people could be selling tickets to somebody like this, to me, is completely unacceptable.
There are other issues that come into play as well, but for me those are the two most important ones.
