My experience with Enigin (now called BEST Energy Saving)

This time, I'll tell you a really curious fact that you can test by youself: If you Google "Enigin" you get dozens of entries, like http://www.enigin.com/, http://www.enigin.net/, http://www.enigin-wrigley.org/, http://www.learningcapacities.com/2009/06/18/enigin-partner/, http://www.enigindigital.com/, http://enigin.typepad.com/, http://www.enigin.me/, http://www.enigin.co.uk/, http://www.enigindesign.com/, http://www.ipodderx.com/Enigin_PLC_Pod_Review_Ian_Wrigley/, http://www.eniginresearch.com/, http://www.searchenigin.com/, http://twitter.com/#!/enigin, http://www.theenigin.com/, http://www.eniginmoney.com/ among others. 

All of them contain similar information about Enigin's business proposal. Why this? Can you guess why they own so many sites without apparent need of? The result is that, if you Google the word "Enigin", you'll find pages and pages of well positioned results containing repeated Enigin's published information about themselves...Therefore, if you're looking for independent comments about Enigin, you'll  very unlikely  find them, being them positioned on a very far and hidden position...

Now, let's imagine that you wish to find in the Internet any possible negative comment about Enigin's business proposal and you  Google "Enigin scam". What are the results? Believe it or not, you'll get MANY Enigin's sites: http://enigin.net/enigin-scam-busters.php, http://enigin.net/enigin-scam-busters.php, http://www.enigindigital.com/enigin-scam-busters/, http://www.enigin-wrigley.org/enigin-scam-busters/, http://enigin.co.uk/about/enigin-scam-busters, http://enigin.co.uk/about/enigin-scam-busters, http://www.enigindesign.com/enigin-plc-quality-design-helps-to-differentiate-from-scam-products/http://www.enigindesign.com/enigin-plc-quality-design-helps-to-differentiate-from-scam-products/, http://www.unoseis.com/enigin-scam/, http://eniginscambusters.net/ and many more...

Now my question is: Why does Enigin invest such a big effort in opening dozens of sites containing always the same corporate information, all of them very finely well positioned? Why does Enigin also invest a big effort in creating sites that appears if you Google "Enigin scam", containing bizarre texts about energy saving activities in which the words "scam" and "Scam busters" appear repeteadly (which help the site go up in Google's position for the keyword "Enigin Scam" and its variaints)?

I look forward to read some answers. More to come...
