Yep.

I had full iron, so I decided to loot someone. Critted him twice, he died, I didn't get the points for killing him and then an infinite health hacker appeared. I critted him 6X (with Iron sword that is 42 hearts, and he was only wearing gold, so no way he wasn't hacking) and he just wouldn't die, and someone else was trying to kill me on the other side, so I got killed. It started because the server lagged, making them appear to teleport to me.

Wut they said.

Plus hits are registered server-side so it may seem like you're hitting people but you're not, you're just lagging.
