i dont think you understand why they are unbanning people..
i am going to say this once, and once only, the devs have already stated why.
They are unbanning people, because FairFight and some GM's banned people, that weren't actually hacking. Fairfight autobanned people, and GM's would ban people if they think someone looks sus, but its so hard to tell on this game if theres someone cheating if they are a closet hacker. ESP for instance, you can easily snap behind you because you saw someone behind you whilst having your char face that direction.
They aren't unbanning because they want to put hackers back in the game, they are helping OG players back into the game who use to play but got banned for BS reasons, they dont know who hacked, there is no evidence, so its easier to unban everyone, on a clean slate, and the hackers will get re-banned if they re-offend. Since theyve done this, population has swarmed back to the game.
