I guess this move makes sense. Why not? They have punished major companies before to set an example.
With every webmaster blaming their seo firm for buying spammy links, google has to set an example to link agencies that buy links.
This is google saying, we will now punish your seo firm if you practice bad SEO. This now will effectivley put in the back of the minds of seo firm if they should rethink their marketing plan for their clients.
