BlackHat has become mainstream and actually necessary in most instances of business. The music industry has used it for years, while people thought every "artist" was painted white (they just got famous because of good content randomly). Wake up to reality, black hat isn't dying, it has become extremely necessary for survival. Also, you need to know that when a public money method comes out, it becomes literally copy pasta until it won't work anymore. When you get 1000 websites that do the exact same method, or 1,000 email submits that promise a free item and then don't deliver you tend to just ignore them and move on. Thus the method now doesn't make any money.
