Spawner campers

Iv been in so many bed-wars quads or trios and have had a teammate who just stays in the spawner the entire game. Can yall make it to where you just die if your not moving for like 1 mins or something.

I feel like a better idea is that they are sent to afk mode and the second they move again their back in  the game. So that it wont kill the player with materials.
