Shooters such as "" have implemented peer review systems, where if a player is reported too many times, multiple higher ranked players are allowed to review the player and determine if the reports are valid, and apply a temporary ban to the player's account if necessary. The player's name is omitted during the replay, as well as those of the other 9 players in the game. In October 2016, Valve implemented a change that will permanently ban a player if he/she receives two penalties for griefing.
