Note, I tend to get restriction #49 when I enter the server control screen ingame (as in, by going into map and choosing server control, if done on logon, or after aborting first it seems to work normally.)
I'll be monitoring that, and requesting a blacklisting if you do ban him for not breaking any rule on YOUR server. thats your warning. No offense, but you're acting fairly aggressively for someone trying to score a pity unban for your friend.
