On Jirue's Bounty Hunter server, manty uses an exploit to know his hunter and shoot him.
This isn't fun for anyone but himself, it disrupts gameplay and because of his "1337 blackhand skeelz" he is virtually unkillable.
I would post screenshots, but It's pretty obvious to anyone who comes to the server.
I even know its a glitch cause one of his friends even just blurted it out.
This is a short drama, but I think it's enough to meet the point that it's abusing a glitch and hurting gameplay by doing it.
