So called 'white hat hackers' tend to be fraudulent script kiddies who couldn't hack their way out of a gibs0n.
They often attend classes like this http://www.infosecinstitute.com/blog/ethical_hacking_compute... and read a book or two like this http://www.google.com/products/catalog?q=hacking+exposed&.... Some times they'll even have a sweet certification like this https://www.eccouncil.org/certification/certified_ethical_ha....
And at the end of the day all they're doing is getting the down low on your system with nmap and then going all turbo with metasploit. And if they are feeling up to a challenge they might even rip someone's exploit from milw0rm.
99% of them are frauds and the other 1% are sellouts.
The way you become a 'top tier hacker' is by exploiting and reversing in the community (black/grey hats). Much of this is done through working with people who you respect and may have more experience than you.
Through this comes a certain level of respect, to where going public with exploits and such is a hindrance to the community and only serves your selfish agenda for fame or whatever.
Your exploiting all the people you've worked with in the past, ripping their ideas, and handing them off to assholes who then try to teach classes on 'ethical hacking' or whatever.
So yes, I'm calling them sellouts.
*Edit - Another problem I have is that these people generally tend to misrepresent 'black hacks' as a whole and try to play themselves off as bigger than life personas.
I mean, I'm all for praising gymnastics, but if we're trying for truth here shouldn't endgame be valued over execution?
Step 1. Open up Metasploit Step 2. Button Mash. ???? Step 3. Profit
