trust me there are atleast 8 cheaters playing on the stage right now, whether u wanna believe it or not :) the cheat coders are so freakin good, they can hide the smooth aim and trigger sooo freakin good, even if u stand right behind them and look onto the screen, u cannot see it.
The only way is if u get cameras onto the keyboard and mouse of all players, therefor u can match the game with their movement, and see anything fishy. just like kRYSTAL with Tweedays filming of him, u can see him using "scroll" as an aimkey. note that many pro players, like flusha and jw, has their middle finger on scroll almost permanetly. Coincidence? I think not ;)
