Jits, I guess I was given the wrong IP. I asked someone in memi irc chan if they had ops, and ComaBull said he did. Since he was not sure how to get the IP, I gave him the command (listip <username>) and he told me the IP that he found. Since you have access to the direct logs, I would believe you are correct.
AgentSmith....sorry if I tarnished your good name, sir, I was merely posting with the information I had. I removed the ban on the IP given to me, so if that was yours, you should be able to access GT servers again.
DT, thx for the clarification on Skaters use of the er33t tag. Skater...sorry for the false accusation.
It does look like this poser was only one person. Originally Dirty Burrito. (or Ur_Master, or Pimp_Ster) He must have started using the GT tag because I called him out when he started using the e33t (and then er33t) tag.
It would be wise to cut this guy out of the game since he is obviously not going to stop this kind of activity. iptables works great for bans, as the person would never see the server again. PM me if you need help with iptables.
Jits, did you search for that IP on the forums? I doubt that he is using the forums as he has not kept a consistent name in the game.
Thanks everyone for your support in this issue. Continued diligence is the only way to weed out the abusers in this game.
