Hmm...neutral. Really can't make up my mind on this tbh. I know you said for an example, if the person made the account when server first came out and ONLY had 47 thieving and so on. Then you could take there name. I guess you could say, "Hey guys, I'm leaving for awhile have no idea when I'll be coming back maybe in the next couple of months. Please have my name protected." If this was a thing, then I guess you could say that? I don't know how it would play out with so many other players.
You can just disappear one day and couple months later be like hey I remember playing this server, try to log in and know that your accounts gone. Like the old saying goes. You snooze, you lose. : /
