I was playing a match and a random hacker joined. At first it was whatever he didn't do much but then he started OPKing. When he started OPKing he was using a spammer at the same time, yet whenever he talked it said "[Admin]" and then his name. When I tried to kick him he automatically crashed the game, but in the lobby it didn't say [Admin] next to his name. Does anyone know what I'm talking about with this?
Also, I can't say out in the open what he was spamming because he was advertising a website's hacks.
