I wouldnt be suprised if this got denied instantly but some way of protexting a spawn would be VERY Appreciated even /lock or World Guard would be anice on a preventive note of people breaking spawners (Its been happening alot recently)
Of course it should come at some cost to the player for having it world guarded of the whole server is going to have no free spawners left, Maybe a fee of 4k per spawner world guarded?
Any compromise would be VERY helpfull to all the players on the server (In my opinion).
