Report bad players here!

Hi guys. I was playing in =RpR= deathmatch (my mick was martufello) and a player named Hitlof Adler connected. He said that he's the player named "N o b o d y": he changed map, so I asked him if RpR knew if he had the adminlogin. He said no. Then he kicked a player named Muller and me. I know this guy, he has the server manager and maybe someone gave him the password to connect him, or anyway he has some program to avoid password, i don't know. I could have banned him but he knows how to unban himself.
Here there's his ip and some screens of the chat.
