Support, I think this would be extremely helpful to the people who either are shopkeepers or just don't want a specific person on their island. For example if someone was in places they shouldn't be, like a trading room, you can get rid of them. Or if they're blocking your way from accessing something you can make them go away. Even if I wasn't a shopkeeper I would find this useful since if I want to /unlock I can only allow the people I want in.

Just because you aren't a shopkeeper doesn't mean you can't use it. Also there isn't any harm in adding it and it doesn't say you HAVE to use the command.

 

Moderators have access to this command. you can also report people for greifing in the report section. but with evidence. sorry, but no support.

 

Maybe another command instead of /ban ..
