Has anyone used Cajole to get paid for dares/challenges yet?

I recently found Cajole.com, which is a crowdfunding platform where people put up bounties for dares or challenges. Unlike some of the older 'dare' apps that died out, this one seems to be from the producers of the movie 'Would You Rather'.

Has anyone here tried an 'Open Call' yet or tried to crowdfund a challenge for a public figure? I'm curious about the payout process and what kind of challenges actually get funded.
