Cobra is the main proof! Once I and Cobra went to play on another server simply and we saw this guy using Warning. We went as we saw Warning in the player's list. And when we started chatting, we came to know that it's Sam. And also, this guy was banned from our server for advertising the server in which he was an administrator. As many knows, I'm having a server. One of the owner of it was the owner of the previous server in which Sam was an admin. That guy didn't ask him to advertise or bring players, but this guy did. As he not even trustful, why should he get unbanned? I've banned him from IRC too.
