Most of my advanced SEO techniques are White Hat,  but I do use some mild Black Hat techniques.  None of my Black Hat SEO techniques will ever be a problem for human beings,  they will just allow the search engines to index your site better.   Just a note:  I have never had any of my sites banned by search engines.

All over the internet, you find thousands of sites that talk about Black Hat and White Hat SEO.  Most people say that Black Hat SEO is unethical, against the rules of Google and other search engines, and you will be banned.  First of all,  the rules of the search engines are in their best interest.  Their rules allow them to make obscene amounts of money and make it extremely difficult for you to make any money.  I say, who cares about their rules, they are just rules and rules are made to be broken.  Plus, I have never seen Google or any other search engine worry about my income, so why should I worry about theirs?
