"there are many negative outcomes associated with allowing or providing for people to simply cancel games without penalty after they have already accepted them."

That's understandable. I am open to finding out whatever negative aspects there are to preventing people from canceling games if they haven't been started. This is a common feature on many other game servers. To not allow it is like not allowing people have guns. The criminals end up with the guns, and the law abiding citizens don't have a means to protect themselves. This is an extreme analogy, but it gets the point across. If someone is to use this feature for wrong reasons, they can still do it now. I would understand it if this feature didn't have a limit, but I think one a day (one a week??) would be very helpful to those that aren't here to cause trouble.
