reading through your comments, one cannot avoid the impression, that your arguments are one-sided. to provide to the people a solid overview of all risks of any pricing model, it takes at least to compare the pros and cons. instead, praising cpa and only linking cpc with fraud proves ignorance. before claiming independence, it is essential to put aside your own bias and broaden your view.
what makes you think that? this is completely unfounded. again: clicks can be tracked, which de facto provides the opportunity to combat fraud. whereas it is impossible to affiliate every sale to its origin, which makes cpa a flawed accounting method in the first place.
