My first guess is that you're underage just because I can't think of any other logical reason and the staff don't ban people just for fun. I'm not going to openly ask for your age though, unless you're willing to share, so I can't confirm my first guess either.

terms of service
state at the top (and the bottom) that you must be at least thirteen. This is in compliance with
. From what I know, you can still play online and talk in servers, but the global chat (or webchat) is disabled because any messages put there are recorded (and might not be removable at this time). If personal information is put in the global chat then it will be stored on the website, which from my understanding is illegal if it is the information of someone under thirteen who doesn't have permission from a parent to put it on a website.
The terms of service also state that you shouldn't hold any of the staff members liable for any issues regarding your use of the website, and I think it goes without saying that an administrator has the right to ban anyone.
