Killing a spawn killer isn't very hard considering there's an invincibility timer, but I see you have one of those gay spawn rooms that makes it easy to spawn kill.
The room you see in the screenshots is the
Class Selection Room. Selecting a class teleports you to the base. But yeah, I agree, I might need to fix them... there's
many idiots I've seen spawnkilling.
After 3 warnings, I kick them.
