First, STEAM (A Game community). It is never a very good idea to hack on steam purchased games because there is always the cost of all the games you have purchased on your STEAM account if you get banned. But You'll probably just get banned from online play. Depends on the quantity of the hacking. (VAC) banned other words.
Second, Play on servers with not many players. Odds are that the more people on the server, the bigger the chance someone will step up and report you via, screenshot.
Thirdly, Don't make it obvious. Don't use a auto aimer and just go crazy. Use it slowly. Just make sure you win the game by "That much"
Fourthly, Auto Aimers are a very good hack. But not always the best. They are the most likely to get you caught in the server, Why? Because the game will show who the killer is. Just like the CoD series, So they will see the "BOT-like" aiming effect.
And Last but not least. Use common sense... If someone says. "Your hacking!" or "I'm reporting you" Leave the server. Because odds are he/she will.
