Users banned for trying to spoil yesterday's festivities have been unbanned. If you're one of those people that registered an alt account and it got ban/purged, then you've got an IP ban on the forums, which means I can't really get rid of it, so you'll just have to deal with it until someone with the proper access can. Please be aware that it's not high on our list of priorities, as you shouldn't have registered an alt account anyway.
In any case, it happens every year, and I always have to say: I don't understand why people feel the need to tell everyone that it's a joke. The fun for us is in fooling people, and the fun for everyone else figuring it out for themselves. Jumping on the forum and saying "GUYS IT'S APRIL FOOLS DAY" is just being a spoilsport; why ruin it?
And FYI, Emperor Whateverhisnameis is on a one week vacation for being an ass. It's fun to play along with the joke, but if you're warned about your conduct, try to take that seriously.
