Skyblock co-op and villager trading

I'll start with villagers, they are able to trade with any player in Skyblock. This is rather unfair since that means anyone can abuse villagers. So I suggest you make that impossible for outsiders to interact with mobs on other islands (villager trading mainly).

Next is the ability to co-op. The ability to co-op someone should be restricted to the perm menu island owners have. (To give members the ability to do something; Ex. Change island biomes, kick/invite members, etc). The island owner should have the co-op ability and be able to give the ability to other members

 

Just block off the area were you have your villagers so people can't use them. And we decided that we do not want to add the co-op ability either because that ability is meant for one person. aka the owner of the island.
