Really?
That page doesn’t talk about SEO, spam or marketing techniques at all.
There it’s talking about “blackhat” in the hacking/cracking term a la security exploits, patch software , cross-site scripting, cross-site request forgery, code injection and SQL injection bugs and the like.
None of it seems relevant to SEO / affiliate marketting at all – and seems to be a completely different issue to the one being discussed.
So again I ask … what takes someone into the realm of SEO Blackhat ?
