For the past year or so, Google has been on a warpath when it comes to link networks, particularly in Europe. That is still going on, it would seem.
Barry Schwartz at Search Engine Roundtable reports that webmasters and SEOs noticed a spike in complaints around manual actions in "the Polish regions," and that one got confirmation from Google Polish Webmaster representative Karolina Kruszyńska. This reportedly said:
Yes, we have taken action against one of the systems to exchange links.
She later tweeted:
Today Google took action on a large link network in Poland.

Matt Cutts has often been the one to talk about this stuff, but he's not with Google for the time being. Clearly, his absence has done little to stop Google from going after European link networks.
Poland was specifically mentioned by Google as an area of action back in July. Other areas Google has targeted include France, Germany, and other areas of Europe.
