I want this player off my island

Chiefghost8200 is a former member of my island but can still break blocks and place them. He has been stealing items and blocks from my shop but I don't have evidence of that :/. I'd like you to completely remove him from my island so that he cannot break blocks, open chests, or place blocks anymore on my island.

 

Just Break a block Under his feet and he will die :>

 

Do /island ban [name]

Then he can't teleport to your island.

 

Did they fix that? Before it just showed the message and didn't actually do anything.

 

Try /is remove PlayerName
I believe that is the command for removing a member.

 

I forgot to mention that he isn't apart of the island, he used to but their is a glitch where he can still open chests, doors, and break and replace blocks.
