Valve has introduced a new feature to Counter-Strike: Global Offensive that will allow members of the community to police problematic behavior.
The program, called “Overwatch,” will designate “qualified and experienced members of the community” as “investigators” who will be given the option to review reports of disruptive behavior, determine the legitimacy of each report, and even issue bans, if necessary.
If they so choose, investigators will be able to review pending cases by examining eight rounds worth of randomly selected gameplay from a reported player, known as “the suspect.” The investigator will then need to determine if the suspect’s actions are “majorly disruptive,” “minorly disruptive,” or if there is “insufficient evidence.” If investigators collectively agree that an offense is severe enough, bans may be issued.
There are a number of factors that determine eligibility to become an investigator, including competitive wins, account age, hours played, Skill Group, low report count, etc. There are also many ways in which investigators are “scored.”
You can catch more specific details on the official CS:GO page.
Valve writes, “during the beta, the system will issue fewer cases and the results will be reviewed and analyzed before any bans go into effect. The system will be adjusted for reliability and accuracy. As the system is tuned, more cases will be made available to more prospective investigators, and eventually the system will become community-driven.”
