CS:GO community task force Overwatch in beta 

Counter-Strike: Global Offensive community members will now be able to regulate themselves due to a new governing system put in place by Valve.

Called Overwatch, members of the elite group will be chosen to watch out for cheaters, griefers, and other ne'er do wells via an "Overwatch button" on their game menu.

When it activated, the Overwatch member will look over eight rounds of gameplay to determine whether the offender noted by other members of the session was indeed in the wrong.

A ban will then be set, and the duration of said banning will be determined by how offensive said actions were.

Should not enough evidence be found by the investigators, the complaint will be tossed out.

The system is currently in beta, and you can look over more on it through the FAQ here.
