absolutely. We get rid of them anyway we can and we have many ways to get rid of them. I'm not sure what game in particular you are talking about. All our servers are streamed to an anti-cheating service (psb) or pbbans
We also get many reports, sometimes daily and we take care of it as fast as we can. You can take a look here Players to watch out for - TBGClan
We are the most professional administrators you will find on net, we cross examine each suspect through a layered spectrum of information sources, discuss each individual in question and created the "ban appeal" template that you see used by other clans throughout the FPS community. we have caught and exposed hundreds of hackers, and its something we are rather good at.
If you are interested or have any other questions please feel free to ask.
