Last month Dota 2 developer Valve issued bans to some of the MOBA game’s most toxic players, saying that they “are too big of a tax on the rest of the community and are not wanted.” Now, the studio is introducing a new system that will disable chat and voice for players if their behaviour drops below a set threshold. In the most recent Dota 2 matchmaking update notes, posted on the game’s website yesterday, Valve includes a section on “Communication and Low Behaviour Score.” In this, the studio says that the last wave of bans “affected only a very small percentage of all players, and we also wanted a more gradual system to address players that are not at the furthest extreme but are still big outliers from the general player population.” This new system, Valve explains, is based on players’ behaviour scores, which the studio uses to track toxic players: “to that end, players that have a behaviour score below 3000 are no longer able to use chat or voice until their score rises above the acceptable threshold.”
