Do you have to turn mob spawning when you use spawners for skeleton or something? I remember you didn't have to before, but now I see a lot of people do.
By default, hostile mob farming is off. If you are the island owner, type /settings and make sure you click the mob spawn egg icon. It should say this when you move your mouse over it.
If you're using a cage spawner you don't need to turn on mob spawning in settings. Since we're cooped, Kbrick has a lot of spawners in place so we have no room for more spawners (there are /limits). You'd have to remove some of his spawners to put more.
