OK IF NOBODY IS BECOMING IN TEH NEXT TIME ADMIN THEN ILL LEAVE RND!!!! 
FOR REAL...
Why do people always think this is the most horrible threat imaginable?
OH NO HE JUST MIGHT NOT LOG ONTO HIS COMPUTER AND PLAY GARRY'S MOD IN A RANDOM SERVER !$#%^&$! THE WHOLE WORLD SHALT END!!!!
Even if an admin was there to ban him, it wouldn't have changed much other than it would have taken less time to re-ban him. There is only so much you can do. We could release a script that could ban by mac address, but this would only prevent someone from rejoining for a little while. Until they finally figured out that we were banning them by that means.
In the end the only way to prevent someone from rejoining semi-permanently, would be to go to his house, cut off his hands, and set fire to his computer, even then if he really wanted to he could still just have someone else log in, in his stead.
So instead of always complaining about how people can circumvent the banning system, just be patient, and keep re-banning him and eventually he will get tired and stop attempting to join again.
People make it sound like it's their right to play on these servers, that if something is amiss it is violating some sort of sacred constitution.
But it is certainly not the case, Coolz provides these servers for the benefit of all of you, for free, using a considerable amount of his free time in the process. He does his best, which is considerably better than just about any other server operator that I know of.
So if things in Random are so horrible for you, that you could simply not find any enjoyment in the game, then by all means leave, because if that's the case then Garry's mod is no longer fulfilling its purpose in providing entertainment for you, so go find a hobby or something that brings joy to your self.
