Support, these endermites can kill people very frequently. People can tpa someone to them and just spam enderpearls at them while they can be trapped in some kind of contraption I guess. That can kill them so they loose their items, but they can just do /is or /home in time unless they are low. Player killing is already bannable so this can fix one more issue of so much people killing each other over enderpearls. The minecraft updates didn't come through with us this time ;c. Maybe, they can remove the chance of endermites spawning somehow. This is the only mob that is hostile too so they can just turn it off that simple. Support for other reasons stated above.
I caught 2 ppl tried to kill me with endermites wihile i was afk. i had pure evidence and Mods did not banned them at all
