Is TVI Express hacking blog sites to post TVI Express spam?

The more I researched TVI Express, the more TVI Express spam I am finding on all sorts completely irrelevant blog sites... like Car Insurance, Abortion (!), Shoes, Band Fandom, and so on.
Here's one on car insurance...  http://carsinsurance.ebloge.com/has-anyone-ever-filled-a-claim-with-nationwide/
Yet it's clear that this blog post WAS NOT about TVI Express. The comments were about Nationwide.  Somehow the content was overwritten with TVI Express spam.
Is there a coordinated attack on blogs to spread TVI Express spam? It is not out of the question... Remember, Ted Nuyten's website was taken down by a persistent DDoS attack when it published a TVI Express expose. So this demonstrated (albeit unprovable) capability of such hacking.
Why spam? Two reasons. 1) It props up search engine and Alexa ratings. 2) it drowns out critics voice, such as this little blog.
