But to the advantage of the good guys, anybody with the brains and discipline to do a better job of this kind of thing, is much more likely to be able to make a better living honestly, than through fraud and deception.
I don't think the business of selling "single mom makes $700/day online" business plans is an honest living, but judging from the amount of ads and comment spam at least a few people are making a living at it (and google of course takes a nice cut as well). From what I've read, even though it converts better than online pharmacies and rogue anti-virus, you can get more traffic to the latter two.
