This is him abusing by shooting. I to told him to stop abusing it but like mastermind said I got the response, "Who cares no one will ban me anyways".
I also explained glitch abusing is an offence if you know what your doing is wrong. And myself and mastermind telling him varrifies that he knows.
I learned though that the only possible way to kill him would be grenades (I think only tazers though).
