Activision has been taking action against cheaters in Call of Duty: Warzone, and these efforts include bans applying to multiple Call of Duty games. Players who are banned in Warzone–and these bans have stretched into the hundreds of thousands of accounts–are also banned from playing Call of Duty: Vanguard, it has been discovered. However, whether or not this is limited to the beta or the full game remains to be seen.
Warzone developer Raven Software is implementing hardware bans, which in theory means offenders can’t simply make a new account because the ban is tied to the particular machine they are playing on. This system is not perfect, of course, but it seems to be working in this case.
