Coinforte, bitforte I have had emails sent from these people, its clearly a scam as nobody is going to just give you 20 bitcoins.
The only benefit I had was with bitforte as I used a throwaway phone number, got in and took 0.0001 BTC as a "validation" for withdrawal, if you try and take anymore, they require you to deposit over 0.02 BTC.
Its a scam, the domains are very new too, but hey I got a free 6 dollars worth of bitcoin.
