But, I think the OP is right. The only successful (for lack of a better word) black hat is going to be a loner.
The DrinkOrDie people got a lot of 3-5 year sentences. http://en.wikipedia.org/wiki/Operation_Buccaneer
DMCA still makes some 0-day exploit research not totally safe, either. https://www.eff.org/wp/unintended-consequences-under-dmca I don't know if anyone has been successfully convicted, but a lot of prosecutions have come up, and that's enough to deter many people.

DarkMarket was an English-speaking internet cybercrime forum created by Renukanth Subramaniam in London that was shut down in 2008 after FBI agent J. Keith Mularski infiltrated it using the alias Master Splyntr, leading to more than 60 arrests worldwide. Subramaniam, who used the alias JiLsi, admitted conspiracy to defraud and was sentenced to nearly five years in prison in February 2010.
The website allowed buyers and sellers of stolen identities and credit card data to meet and conduct criminal enterprise in an entrepreneurial, peer-reviewed environment. It had 2,500 users at its peak.
Legal advice is a big part of black hat literature, so I don't think any of them can claim ignorance.

Error! You may like "serving one's country", but you have no business claiming it is inherent in honor, morality, or integrity.
Some kid with no record gets thrown in a van by men with guns, and the full force of police psychological manipulation is brought to bear on them. They get told they're irrevocably destined for a lifetime of being brutally raped in the showers.
Is it any surprise that these young men with no experience of foul-play or maliciousness outside of the virtual world fold and turn informer with such regularity?
If I were an active blackhat, I wouldn't talk to anyone, ever. I wouldn't even invent a pseudonym, that's the first step to ending up on fox news.
