Activision rolls out a Call of Duty: Warzone ban wave and promises that Modern Warfare 3 multiplayer is next: 'Leaderboards have been purged'

The picture accompanying the post shows how an account at rank two somehow managed to make positive SR gains in almost every match—out of 18 games, 15 were positive SR matches.

Another player also points out that these accounts may not even be technically cheating. It's also possible for players to use VPNs to queue into a lobby full of bot accounts to farm hundreds of kills per match, guaranteeing 300SR or more.

Are they forcing you to make skins? You can speak out. It’s safe.»

The shadow-ban system relies on reports from other players. If there's someone who is seriously good and dominating in a match, someone can spectate
