I just deleted these usernames: 

px1234 
px 
lol 
admin 

They all registered today around 12 noon and they all have superadmin privlages. I apologize if one of these are anyones username. 

I'm not sure who it was but sometimes Teamspeak hackers come to TS servers with a username like this "NAME R SA CA" which make it appear that they have server admin privileges and then they ask something like "How'd I get server admin privileges, can you please take them off" and when you try to do that you actually give them SA.
