It's bait and not even worth that much.  Only $10 they are giving out (if they give out that much, many report getting far less).

Stellar-Stripe ("SS") have 5 billion tradeable Stellar versus the 300 million they traded out.  They're also sitting on a 99.7 premine being 99.7 billion out of 100 billion coins.

It's one thing to receive free coins and to dump.  It's another to buy coins as Stellar-Stripe pretty much controls almost all of it.  It's pretty much Ripple but with a free buy in which is popular with blackhat hackers with fake facebook accounts and third world people.  Many people are saying they acquired millions of Stellar by advertising to people in India to claim Stellar with their facebook accounts and sending it them to for $5.
