There’s hackers pretty much everywhere in the game such as: XYZ, Papi Chulo, KaiDragon, and many more. This issue won’t get resolved until developers do something about it (starting to believe they can’t).
Many GP’s probably don’t even try anymore because even if they ban the player, it’ll make a new account, bypass the ban and continue cheating. It’s more easy to ban someone with “sh*t” on their status than trying to ban a hacker.
