850,000+ Warzone accounts banned to date. I’m sure a few of them may have been false positives but the majority of them were not. With that said…
Although we don’t know the exact number of banned players here in Battlefield at this time, I’m sure the ratio of illegitimate players to legitimate players is similar if not greater than the Warzone numbers since the Battlefield franchise has never truly had a fully working anti-cheat. EAC is still nowhere near perfect by any means, but at least EA is now taking small steps in the right direction with their ban stance on cheating and Toxic player behavior in games.
By Toxic behavior I don’t mean someone doing a friendly T-bag opponent grudge corpse taunt in game. I mean one or more players intentionally interfering with another user for no other purpose than to grief, ruin gameplay, make the game unplayable, interrupt the game and make it unenjoyable for others. Here’s just a few examples of Toxic behavior (software cheat users are a completely different story) that I've encountered in game. It's done repetitively by the same group of players match after match...
-Spawning your teams’ vehicles and handing them off to friends on the enemy team.
-Stealing vehicles and then driving them out of bounds with teammates inside just for griefing purposes.
-Stealing vehicles that are defending control points and driving them off so friends on the enemy team can take the point without resistance.
-Spawning vehicles in the start zone and just sit there, keeping them unavailable for your team to use during the match.
-Use vehicles to push and hold another teammates vehicle out of bounds until they time out and die.
-Purposely flipping teammates vehicles by ramming them with your own to grief your teammates and kill them.
-Purposely deploying fixed items for no other purpose than to block your own team’s advancement.
-Purposely and repetitively using your body, vehicles, or deployable objects to block shots made by your teammate’s gunfire towards enemy players.
-Purposely standing on top of or next to a teammate’s location or vehicle shooting at nothing or shooting in the direction of enemy aircraft as tracer fire for your enemy friends to see and grief kill your teammates.
-Placing explosives all over a teammates vehicle that you're not riding in and when it is hit once by your friends on the opposite team the vehicle will explode in one shot.
