This is myth! BlackHat SEO is not that powerful as you think. Blackhat systems usually works for no more than 2 weeks and do not get that much income. Just like white hat working, most works only for e-book sellers! SEO just need time, no matter white or black
People who try to earn money from Black Hat sites are going to get a burst of short term profit at the very most. People who leverage Black Hat techniques and use them to help their White Hat sites have a massive head start. Personally, I research White Hat, Grey Hat and Black Hat as one and the same. I take what I like and what I can see money in. Anybody who dismisses Black Hat without a second thought is a blind fool. Though of course, you won't find many good examples of empires built on Black Hat. That's because staying under the radar is so important.
I love short term profits, especially if they could be duplicated I am not black at all, but today was searching something, and came on SEOblackhat again, and wondered is it really worthly to pay that amounth monthly
