Earlier this month, Google revealed that it would be cracking down on more link networks, following a larger trend that has been taking place throughout the year.
Google's Matt Cutts hinted on Twitter that Google was taking action on the network Anglo Rank.
"There are absolutely NO footprints linking the websites together" Oh, Anglo Rank.

He went on to note that they'd be "rolling up a few."
On Friday, Cutts tweeted similarly:
"Our installation code/software used to publish the sold links is not detectable by the search engine bots." Au contraire!

This was apparently in reference to another network, BackLinks.com.
No surprises really, but Google is making it quite clear that it's going to continue to penalize these types of sites.
Hat tip to Search Engine Land.
