I feel like I would love to use this, but I would be worried about HR freaking out. I had a training before being allowed to interview people and it mostly consisted of teaching how to avoid questions that might inadvertently provide you with information that could be used to discriminate against people that was also irrelevant to the actual job (e.g. don't ask "what do you like to do on the weekends", but you can ask "this job requires you to be on-call on weekends, is that something you are able to do?"). Going on a website specifically advertising that it has people in a specific class seems like the exact opposite of that.
