I work at Stellar. We wanted a method by which we could fund people once (to prevent someone from spinning up a lot of fake accounts to claim) hence the decision to move forward with Facebook. I know it isn't perfect, but we are doing our best to make the giveaway broadly accessible and not game-able. And we are working on other claim methods so yes, totally hear your concerns.

I like that because your friends and photos are a lot like a social fingerprint. If there are no photos and no friends, then no Stellar.
