I just wanted to say if you figure something out and are making money from it, I would pound it and milk it until it's dry. I was lazy about this one technique I had that was making good money for me, but I couldn't put in the hours and it dried up (I'm still trying to make it work, so I'm not going to out it yet...). Things change quickly, so if you don't capitalize on things you know now -- it'll be gone in the future because other people will abuse it until it's dead. And also, I believe that the money you make from blackhat should be invested towards things that are grayhat, which should be invested into things that are whitehat. Ultimately, you want to be earning a living from your whitehat income, supplmenting and growing it with blackhat and grayhat income.
