I find it funny that 'over 50' have been sold and yet all of his 5 Sitepoints came as a Buyer. He wants you to send him $5 but argues with his potential customers and will provide no proof - to me (and obviously others), that spells SCAM.
"i know the SUPER-SECRET RULES the EXPERTS wont tell you!!!" yeah, seen that a hundred times before about "make money fast", "loose weight (fast!)", "make millions while you sleep" etc...
I've got an alien in my basement, I'll sell it for $5, but I won't even show you a picture before you buy. Maybe you find my ultra secret basement and try to kidnap him....
