After seeing a few custom settings (such as the wheel zoom) and seeing a thread posted (see below for link) I would like to know from everybody's point of view (server admins and devs especially) what should be considered legal or illegal to use in-game. In my opinion there are only a few things that should be considered illegal and they are: wall-hacks, aimbots, movement/strafe bots, trigger bots, and radar hacks. I noticed however that a few people have been griping about so-called performance hacks (stripping textures and such down to improve visibility) and similar tweaks. I myself stick with cranking most of the graphics up and the only hack I've toyed around with was the wheel zoom.
