I have always agreed with what you said Webzcas, but the fact remains that these sites continue to be a huge issue for all of us and have not gone away on their own.
Its always preferable to take the high road and I would never advocate using Blackhat SEO to promote or optimize sites for teh search engines, I do however think its a totally different question here.
What I am pondering is using Black Hat techniques on those using Black Hat techniques to steal our traffic and rankings. Copying other peoples hard work and content is as low as anyone can possibly go, for people like that there HAS to a response. Pascifism doesnt work with these assholes. Beating them with their own methods will.
Again the objective is NOT to acheive rankings its to make sure the pond scum does NOT profit through the hard work of others.
