If you're admin only I don't see a problem.
If it's in a tourney, and you're about to go up, you can constantly keep nudging yourself down so you never have to fight. You'll end up in finals. That, or other people will start doing it once they find out you nudged down, and the entire server will end up nudging and nothing will get done.
Let's say I'm the 4th on the server. I went to grab some food cos I knew I had some time before my match. But when I came back I would found myself afk cos 2 guys before me decided to visit their toilets.
