you can get banned for it, although only 1 - 2 gm's actually come on server 3 daily, if u are screenshotted doing it and they get their hands on it, they can bann u with a lifespan of 10 minutes to 20 years. So be careful if u do happen to infinite a room, and trust who u infinite it with.
the reason why u can get banned for doing boss infinite glitch is practically speaking for itself... it is glitch/bug abuseing.
so be cautious and dont complain if u may get banned for it.
