Call of Duty: Warzone Bans Carry Over to Vanguard

Activision's efforts to stamp out cheating in Warzone have apparently transferred over to Call of Duty: Vanguard, where cheaters who have been banned in the first game are finding themselves unable to play its new sequel — at least in the beta.
Developers combating cheating have more than one kind of ban they can apply to offending players. One is to ban the account, but that punishment is easily evaded by creating a new account. Slightly more effective is a hardware ban, which prevents a player from playing on the same machine no matter how many accounts they make. Although there are still ways to circumvent a hardware ban, it's more difficult than making a new account.
@ATVIAssist I am shadow banned on vanguard because I am permanent banned on mw ans warzone, and I might get permanent Ban on it just like a guy that I know, so I just spent 60 euros to get shadow Banned on a fresh game, at least tell people that that’s the case, such a bullshit!!

Per reporting from Eurogamer, bans appear to be carrying over from Warzone to Vanguard, regardless of their type, frustrating cheaters who have been struck with bans in the past. Eurogamer and CharlieIntel cite cheater Discord servers and forums that show players unable to log in.
It's unknown if these bans will also carry over to the game's full release, but it seems likely they will. Activision has also announced Vanguard will bring a new anti-cheat system to Warzone when it launches later this year.
