I'm not sure what the problem with it is. A noble at sea cannot actually do anything, and is not immune from banishment.If someone wants to "exploit" this to run away from retribution by his realm's enemies, he's mainly just going to bore himself.
Also, if you try to go at sea while rogue, you'll be forced upon the realm selection page as if released from prison.
Lets say hypothetically their hiding at sea allows them to basically troll a lot of other players.
So...either you mean that they're in the same realm, and sending loads of messages to the players in the realm (in which case they can be banned), or you mean that they're trolling people outside their realm simply by being inaccessible—in which case they could do the same thing simply by pausing.Neither of these is a real problem.
I was thinking trolling a religion that way. If they're a priest they can't be kicked out.
I don't see how that's different from trolling a religion while hiding in a realm that's friendly to them.
I'm concerned his last resort will be taking to the seas.
Out of curiosity, what happens if you're banned from all realms, and you get to the page where you have to pick a new one?
I don't think it has any code to handle that yet.I'd probably give the guy a medal, then force-deport him
