ive been looting around my island trying to find a swamp biome as im spawning every mob i can, and i really wanted to spawn a few slimes please can someone change my biome

 

Every island is in a Taiga, and you cannot have your biomes switched or island moved into a new biome.

As for "Looting around your island" I dont exactly know what you mean by that, but let me just warn you that looting and bridging outside of your island are both illegal on the server and if you are doing that, I suggest you stop.

If you have any more concerns about this, pm me.
