Well someone by the name Cakeygiraffe, http://wls.gameme.com/playerinfo/473529 thought it would be cool to tell the whole server about a map exploit with mg_3k_smash_legocopter.. Now pretty much everyone in the server knows about the exploit. And everyone is doing it.

Theres the demo.

Everyone from SG knows that and would use it all the time, and since many people from SG play this server it is quite well known. I would not of shown everyone it but everyone including you was going to demo me for hacks anyway. It is, in fact, an SG map that the maker probably exploited himself.
