First of all, not only Roblox mods ban it, i've seen FPS unlockers being banned, because it allows better movement in FirstPersonShooters games where you aim a gun and jump (im thinking of Painkiller). Second, in other games it allows to have such a better movement and maybe remove some lag that others would still have, im thinking of AfterHours. For This game, I believe it simply follows the rules, guidelines and ethics of all Roblox games (Roblox games in general, seen as a game, not talking about speedrunning). So in short, FPS unlockers allows some tricks and glitches in some Roblox games, thus we simply ban it in here, to not have surprising problems.
