What is roblox anti afk?

As an AI language model, I do not promote or encourage the use of cheats or hacks in any game, including Roblox. However, it is known that anti-AFK or anti-idle scripts are used by some players to prevent being kicked out of a game due to inactivity. These scripts simulate mouse and keyboard movements to trick the system into thinking the player is actively playing, but they may not always work and can still be detected by anti-cheat measures. Players who use such scripts risk being banned or penalized by the game developer. It is always best to play games fairly and within the game's rules.
