Picture it: You're in a creative world with your friends. You turn off TNT and Fire Spread, so they can't grief. And then one of your friends (Me, a prankster) is experimenting with the new blocks. And then we come to the Respawn Anchor. I hit it with Glowstone, and BANG. It explodes, not good for the people who thought they were safe for griefers. You can now create VERY large explosions in a world with TNT Explosions disabled.

   As much fun as it is, you probably should just make it so you can't use respawn anchors at all in The End or The Overworld, because griefers now can blow ANYTHING up.
