Some players have shops and advertise them, like in /ads. However, sometimes their island is locked and they don't realise it. So what you have is players trying to visit that person's island, either via /ads or via /visit, but they are unable to and instead receive the following message: "[player]'s island is locked at the moment and you can not visit it!".

My suggestion is to implement an optional message toggle that reminds the player that their island is locked whenever someone tries to visit them. This could be enabled via island settings, just like the message that tells who visits your island.

The message could say something like "[player] is trying to visit your island, however your island is locked!"

 

When your too used to /L trying to go back to your island like most other servers and forget to unlock. My mind working backwards

 

neutral. message could be spammed. if there's a way to counter it, i'm all in.

i suggest that if someone wants their island to be on /ads, then putting your island on /ads should make it unlocked and you can't lock it until the ad goes away or you disable it.

 

if the message is being spammed, the player can always disable the reminder, however it shouldn't matter if the player is afk or something.

I agree on the second point about not being able to advertise with a locked island.
