I somehow ended up receiving mail from a Dani Mendez from a company ironically called Gurubusters.com. [Kind of gives an impression of righteousness]
I have now seen one example of an extremely bad deal for an overpriced affiliate product, one advert for pyramid selling a exhorbitant, misrepresented supplement, and an advert for a deceptive home working scheme, which takes $50 from people, having misled them into thinking they are going to earn silly amounts for doing 20 minutes a day data entry, which never seems to happen (surprise). I feel sorry for anyone lured into these sorts of rip-offs.
I think anyone reading this should be able to draw their own conclusions about how to respond to such "opportunities".
