I vouch for this, somehow he was able to get on the roof, and then when you TPA people there, it has a high percentage rate of killing someone, which drops all the stuff that they had, allowing himself to get the items. NOTE; He didn't use the exploit and abuse it, he was showing people it and lol. I got -2 power from this.
No, they simply build "traps". This is not a glitch. You just dig a really deep hole, place an open trapdoor on the edge, then accept tpa's. People will appear on the trap door, but since it is open, will fall down to their deaths.
Or just get close to the edge of the block and the people get teleported to the nearest block of the centerpoint of your player entity.
Yep, some people take all their gear off, tpa then set home. Unlike others, I know a glitch to bypass the traps. So I go with all my armour. Want to know how? Pm me.
