Many many times again people always /tp to other people soon just to kill them. Whether that's survival, factions, or maybe even skyblock. Nowadays we can't trust each other when helping each other. How can we prevent this? Well, I think I might have found a way... When tp'ing, we could have a 8 second tp prevention in which we can't kill each other. Simple? Sure! During the time of 8 seconds, you can have a choice of 1. Tp'ing to spawn/home. 2. Run away. 3. Stay and get killed. What's your feedback! Anything will do!
The only problem is when you use Enderpearls it counts as teleporting, so when you through an Enderpearl there would be a 8 second attack delay. It could become an exploit just like the Pressure Plates.
Good point. However I think in the files we can find a way to go around this. Y'now. Without the endear pearls.
