Yes, I tried it.  They gave me 100 FACE tokens, which are sitting in my ETH wallet to this day. 

However, I'm fine with it -- I provided an anonymous identification to the verification engine and it still worked, so -- those who are worried about anonymity, you can still make up a FB profile and link together. 

I have no idea if this will be a successful project or not.  However, I tend to hold onto my ALTs for better return.
