You have to understand that in an online community people judge people by names. This doesn't apply to the real world (not as much at least), but it would, and people would judge you (or at least your parents) if you said "Hi, I'm s992mazzz." And this definitely applies to the online world of Minecraft where there are griefers, I constantly check names with a lot of numbers in them more than others, and its easier for your name to mean something to people if its simple.
Due to a very big problem with Summoner's Server with griefing all the time,We think we are a big target because we go to the top and have lots of people on. But we are deeply sorry of banning/kicking you. You have been unbanned
