It is called viral marketing lol
I just got off the phone to the main man himself, Richard Elis. I expressed my deepest concerns and frustrations with not being able to access my coins and he gave me a secret code to claim FREE COINS. Use code: XXXXXX - it will work for anybody!
Thats a very nice try to attempt to fool some naive users. I have replaced your code in the quote above.
At least the other spammers tried to be honest about the referral code.
