Sorry I just joined the forum, I guess I can't really prove it unfortunately. Yes it was on BF3 server. If I see him again ill join his team and try to get some video of the cheating. There is some other people too that come in having ~300 pings and mow down a ridiculous number of kills.
The real problem is not the aimbots, its the sneaky ones that only use the radars, wallhacks and so on that pretend to be legit. But when someone finds you in a dead alley in a corner on maps with nobody near you and headshots you, it raises my suspicions
Thanks for the replies I'll try to get some videos for you guys so you can clean it up.
