I tried to buy 0.1 bitcoin via SMS on btctrade.org/freebitcoin.nl are scams. Both are run by the same person (Marek Skorek) and were the exact same design until he started redirecting one to a wix site. If you contact him on facebook (https://www.facebook.com/gratisbitcoin) he blocks you. He even has a scam site pretending to donate to the Philippines http://bitcoinaid.org (which also uses the same design)! No class at all...
Leave him bad feedback: https://bitcointalk.org/index.php?action=profile;u=85062
