Since you're allowing people to donate to charities or "anti-charities," you should just allow the user to specify a % fee that goes to you. If I set up a $1,000 contract to go to some Nazi org if I fail, I'd much rather $1 go to the Nazi org and $999 to you.

Sounds like you'd be more motivated to hit that goal with the payment distribution as is.
