Serious question. How concerned are you that the machine could "dare" someone to do something that's actually unsafe or dangerous. (Couldn't you incur liability for being the ones who sold the service that issued the dangerous request?)

As for how I feel about it: I was going to suggest you name it "Do whatever the machine tells you to do." But that's mostly because I think part of the fun of truth or dare was that it was mischievous humans dreaming up the dares that they'd like to see performed. My backseat suggestion: now that you've got a critical mass of users, maybe try "crowdsourcing" those dares like on Reddit -- with upvotes/downvotes and comments. That might get you genuine human-crafted dares, without anybody having to obey a machine.
