"corporate front groups were disseminating the pro-Big Business propaganda to slant the news we read but this is a bit of a rare glimpse behind the curtain as to how it is sometimes done. In many cases, they actually pay for bloggers and professional "trolls" to write for them, submit letters to the editor and op-eds to newspapers, downrate articles on sites like Reddit, and give bad reviews to liberal books on places like Amazon.com while uprating pro-business books. In this case, they are fishing for free exposure from bloggers, apparently without checking first to see if the bloggers actually agree with their corporatist agenda."
