Understanding In-Game Script Kicks & Bans

2. If kicked unexpectedly, check if you have background macro tools (AutoHotkey) or FPS unlockers open, as game anti-cheats flag these.
3. Try joining a completely different Roblox experience to verify whether the restriction is game-specific or account-wide.
