I'm going to be blunt here. Why the fuck are you doing this?
Instead of improving or maintaining the site you've decided to become the babysitter of those who can't be responsible for themselves? I'd imagine the people wanting/using this feature are the ones who bitch and complain when they want out too wasting more of your time. This is an extremely confusing and disappointing business direction if this is where JustDice is now going.
I did it because I didn't think it would be too much work. But people aren't reasonable. I regularly have people trying to break the terms of the deal they themselves came up with.
I'll let the existing deals run their course and not enter into any new ones.
