I suggest you spec and record more then. If it is clear someone is hacking, i`ll be the first to hit the banhammer. Believe me if i say i litterally got hours of gameplay form certain players. The ones that cheated are lo9ng gone. The ones i doubt can stay a bit longer, so i can get enough proof.
The small clip you provided is not enough for me to ban a player. Never has, never will.
I can give you my word that if something like this id presented to our admin team, we discuss it and i can promise you, there is enough gametime and experience in our admin team to see if someone is legit or not.
Also, i would ask you to not take things on our server to the ingame chat. That only stirs things up. (I saw a crapload of people talking about the clip). Rather hop in to our TS and contact an admin, or indeed, make a post on the forums like you did.
