Battleye is an anti-cheat software used in various online games to detect and prevent cheating. Players can get kicked or banned if Battleye detects suspicious behavior or unauthorized third-party software. Kicks are usually temporary disconnections, while bans are more severe and permanent, removing players from the game. False positives can occur, but Battleye has a robust appeal process. Staying within the game's terms of service is crucial to avoid being flagged by Battleye.
