Usage of black hat SEO

Hi everybody, I am first time in a black hat SEO. Black hat SEO is not liked by search engines but black hat SEO exists at a remarkable quantity. I want to know in which purposes I can utilize black hat SEO.

Please not just touching answer, but I need real suggestion.

I could be wrong, but... You can use blackhat SEO to FUCKING RANK YOUR SITES IN THE SEARCH ENGINES? Just a wild guess.
