Yes, Rockstar IP bans players that break community rules. That includes using mods, exploiting in-game mechanics, manipulating your game data, and, of course, misconduct towards other players. You can receive a temporary or a permanent ban, but either way, you’ll lose all your progress, property, and inventory. Keep in mind that Rockstar doesn’t allow appeals, so if you get a permanent IP ban, you’ll need CyberGhost VPN to hide your IP and get back in the game.
