Chances are if they are spawn killing you they have the potential to break your bed very easily, why not just leave?
[Edit] Yeah, you could see it as an unfair way of getting kills, that's debatable, however, there are so many different cases of spawnkilling that getting proper ban evidence would be extremely difficult, soooo many false bans would occur.
Do you not get what I'm saying? It's perfectly fine if the player deserves it, but what you do is just low.
My problem with this suggestion is that if a player is on your island ''spawn killing'' players... your bed is gonna be destroyed in a few seconds (under most circumstances at least). So you'll be dead anyhow. And if someone is in proper gear it won't matter whether you run a few blocks out to hide or engage them with your fist. Your intentions with this suggestion are positive. And with that my opinion says no (or as you prefer it ''no support'') for this suggestion.
This is what I'm not against my point of this suggestion stands quite like this: "Player A spawn kills while Player B farms gold or help spawn kill instead of getting the bed, therefore making people not want to play, and making players leave Mineverse."
This stuff happens? Lol, I rarely see anything like this happening. My opinion stands until I see this happening in a game where I'm in.
Support! It's annoying when they don't break your bed, and farm kills at your base. I just can't respawn, can't quit the game, it's really annoying. Double support. Triple support.
