Keep me banned for a bad avatar and for having a username of "Hunga Chunga"? That is what I was banned for you imbecilic bad admins. A sane person would of warned the person first, what should my avatar looked like to make it "good" for the admins standards? And what username should I of chosen? Seriously, the rules on this server are ridiculous.
1) More than likely the ban was not permanent. I have only seen a few Permabans with the WB admins. You should have been happy this wasn't Bluzone. You would have been perma'd and post like you are would not have help whatsoever (not like it is here either).
2) Your username is relevant to this, unless your talking about the name you selected. That is another story. Like if you really selected that as a name, I would expect a ban.
3) Not sure what your avatar looked like, but I can imagine that if the admins did not say, "Please change [body part name]" then it really must of been bad. Plus in the room where you select a entry point, it warns you to have a realistic avatar. If you don't know what one would be, or if you want to make sure, ask. It never hurts to ask if something is allowed.
4) Name choice? Sometimes names are hard to pick. I have a few websites I use to generate names for me. 
This is the main one I use, although you must be careful because some of the names are not ones that are usable. Go to any baby name picker for some good names.
5) The rules are not 'ridiculous'. If you really think they are, then please, don't play here. They rules are in place to ensure proper and fun play for serious RPers. The rules make sense and work well. I haven't broken a rule yet (mostly true, a few jokes and one rough time) and I ain't banned. Break the rules and you will be dealt with. The admins on this server are very nice though. They forgive quite a bit, and second chances are not that hard to get.
Personally, with how you have acted in this thread, I would say you are a demanding person who puts yourself above others. I would not unban you and increase your ban time.
Thanks for reading =)
