Wow... hadn't seen it, glad it stopped here or least hoping it did...
I really couldn't imagine a more pernicious effort to poison already strained interpersonal relations in America if I tried.
I don't think your project is illegal but it is clearly, morally, reprehensible. You should be ashamed of yourself. What you are doing is a "bad thing" - on a pretty high scale of "bad thing".
A while back yummyfajitas asked how Wikileaks would be judged if someone died because of their revelations. Can I ask you the same question? What would you do if one coworker initiated violence against another because of your rating site? What?
Not only do I want this to fail but I think it should rebound on your other projects ... hard. I don't quote The-Jesus much here but here, "Judge not, that ye be not judged" comes very much to my mind.
Seriously, this is so bad that you need to take it down NOW and apologize.
