Just ban him. He did it more times, warning doesn't help it seems. This. He's always doing it, I won't mind if a new player does it once or twice because he didn't knew it was glitching but that guy got even told by lots of people to stop glitching and I wasted around 15 minutes with just telling him to stop it, he either answers "who cares" or keeps spamming "oh shi". Next time I see him I will get a screenshot/video of it.
