They are using a program called "Auto Hot Key", a program that you can macro to auto press keys. So one could tie running forward to Q spotting and constantly spot everyone you look at as you run forward for example. This is being used by a lot of "top" players, and its really not fair considering any new or newish players, who are already at a marked disadvantage, are even more so because of this cheat. This would exacerbate new players not sticking with the game, which is a shame, because we need fresh blood to keep this game alive. If you were using KAMU's Easy Anti-Cheat, you could configure it to detect any 3rd party program as something considered cheating for your game, and take appropriate action ( terminate client, report user for cheating, etc ). Very easy web-based interface to see a summary of all goings on. I recommend Easy Anti Cheat, and more diligence in detecting hackers and exploiters, which in a shooter game, is really the death knell of the product. As to all you players using this, you don't need to, and that shows weakness that you do use it. You aren't helping to maintain the game by exploiting it, and driving away fresh blood.
