They can argue that everyone has paid for the game and can therefor do whatever they want with their characters with no restrictions (outside of the obvious things that can get you banned.)

I'm all for the AFK kick timer...but think it should be set to an hour. And I also wouldn't be selfish and leave my game on all day until I get home from work to ensure I have a spot, haha...

I'd like to think a moral compass should come into play for a lot of people. :-P
