I was on Daqing just now (6:40 PM CST) and not only he's impersonating admin, he's also C4'ing teammates, ramming his own team's jets and just being a major nuisance.

The fake ban and kick commands I believe you can find in the log yourselves.
Circumvented a ban to do it, but I set up something special for his return. If he somehow bypasses this one please post something ASAP. Preferably while he is still on.
