Player leading people into death traps

A player named TriglyOnak led me to his base and got me to save there and then got me to walk into a death trap luckily I alt tabbed and closed the game and when I opened back up I hadn't lost my stuff. I just wanted to let people know to be careful.

Edit: Not sure if turning PvP off works when it's a doorway that when you walk into it you burn to death but thanks for the advice anyways.
