I was on Albeist's server, running a Push Broom DM, xLEGOx starts spawning cannonballs into my minigame's building. I called Albeist (host) to see what was going on. xLEGOx immediatelly deleted the brick that was spamming cannonballs and pretended that he hadn't done anything. After a while, when the host was AFK, I created a gun deathmatch and he starts spamming rockets into it.
This time, I managed to gather some proof:




Seriously, what the forget? We were just having a good time in a nice vanilla Gun DM and this friend comes and ruins our good time. Because of idiots like xLEGOx, the world has to perish. The world has evolved this far and return being insignificant. Can't we just have a good time? Is this only your method of entertainment? Learn new material.
I say, I'm not overreacting. These kind of people are everywhere, including in the streets. Just keep this guy away from your server.
