Spamtech is an off-shoot of esrun.co.uk that primarily offers software, browser extensions and php scripts for use by blackhat and whitehat seos. I have several years of experience in the SEO industry, having worked for one of the top SEO agencies in London and helped setup and  then manage one of the largest outsourced link building operations in the world for over 3 years. And I’m not talking about low level spam links, but rather high end contextual links.
