I'm genuinely surprised you responded the way you did to this. I expected you would be perfectly okay with doing a minor fix to prevent this whenever you felt to do so. I didn't expect you to fight the idea at all, so you've caught me off guard. Comparing building a box to making a teleporter trap, you only need to set down two bricks, and the script forces the player permanently in place. Of course Ctrl+K or F8 can escape this, but the point is it's much quicker, and sudden to the victim, to build in comparison than a box or spamming bricks. I guess I could also mention you don't get as many warning planting clicks.
If it's any trouble, you can pass. As a personal opinion, I think it's are to easy to grief using this, but my opinion doesn't really matter.
