Blackhat is not a good business model for affiliates (or affiliate programs) to follow because this industry is all about trust. The moment you enter into the shady area of rigging search engine results is when you start to lose integrity and lose out financially in the long run.
Sure, there are immediate financial gains from Black Hat SEO but it’s better build quality content and a respectable informational website and then ask people to reciprocate your links to them, yes, I know it sounds boring and I know that reciporical links are not as valuable as one-way links etc. but it does help.
I will also be a little less inclined to work with a “Black Hatter” because I know they are short term investments and I’d rather help smaller affiliate build their website(s) and client base.
As for posting at Matt’s blog. You don’t mean Matt Cutts from Google by any chance? Hrm, I am not sure what CAP’s policy on “outing” affiliates or webmasters. Perhaps you should get an official response from Professor!
