Canter around social media sites, a girls chat room etc. How long has she been around? Does she seem to play nicely with other females? Who else has she worked with on cam/in adult? (and what do you know about those people) Cross reference. Research. Does she have frequent mental break downs for the entire world to see? Yikes. Hide your kids, hide your wife! Not everyone you think is a good friend, is indeed a good friend. Use common sense. Mind your own business. I mean that in many ways. Mind your own BUSINESS, so it grows. The more positive you are and careful who you surround yourself with for support and collaboration the better off you will be. Don't let negative people suck you energy or motivation. Doing so, the more successful you will be. And when you think you've found a chocolate chip (friend) and instead it's a raisin (foe) you can learn that lesson and be more careful. Hint: I had to learn this lesson.
