I can ban somebody on my own server, edit the console log so it looks like somebody else did the ban, then copy and paste it over and over.
have another look at the console log, the numbers go up
So unless he copy and pasted over 2000 bans and then manually adjusted the numbers to increase by 1 each time, i seriously doubt your theory
And yeah, as pablo said, there are scripts to be able to do this, Mr. LoL very well may have one.
