That one is a ponzi
The advertised sight might be a ponzi, however that doesn't automatically make his signature deal a fraud.
I would expect it is, but I guess there's nothing to lose trying, as it's either that or nothing.
True, but some may find it unethical and immoral to promote a ponzi.
Of course, but I assume everyone would personally check what site they were advertising for if they had such moral dilemmas.
