Sure, people accuse people of hacking, and sometimes they are wrong. But when there are people on the server with a score of 100:2 it is slightly fishy don't you think? And when that person is running round the map at 10 times the speed of everyone else and is spinning round then you have got to admit, it is extremely doubtful that they aren't hacking. You are right that some people are not hackers and may get accused of it, probably because of a few lucky shots, but there is no doubt when a real 100% hacker is on.

Really all you can do when a hacker is on is say something like "Admin is in RCON mode now, they will be banned soon", start a vote kick, and hopefully the person will leave because they don't want to be banned. I am happy to give out more admin to the newer members, but they must be active on the forums before I can be sure.
