I don't think its an exploit. There have been lots of trending pictures of this happening to people. It is a bug...
Also their ranks don't really seem like the kind of people who are propelling themselves upwards with exploits...
I think its pretty rude to accuse someone of cheating without any proof in a game as buggy as CoH2
Iam not proud of what I wrote in gamechat but I think that the OKW Player is admitting that he uses this bug as exploit.
He answers with "Don't you say" after I tell him that this is clearly exploiting a bug...
Also this guy has a VAC Ban on his Steam Profile so I think this guy is exactly one of these guys who try to cheat.
