I have been playing on these servers for a lot of years now, and yes it is very frustrating getting your ASS handed to you round after round. But I can assure you the Admins will deal with it if you can video the proof.
But like it has also been said we have some amazing players that use our servers that coupled with decent rigs and pings make them look very suspicious.
Even a decent headset can make one hell of a difference as i have now found out to my benefit after investing in a new one a few weeks ago. I can hear people coming round corners or sneaking up on me (some of the time ?).
Just relax spectate them and get the video. Then let the Admins take out the trash ,
But please to save drama make it private so only the Admins can see it that way only the guilty will be aware when they get banned, and the genuine good players do not have to waste there time proving their innocence on a public forum for all to see Because Mud Sticks and it should not need to come to that.
