Karolina Kruszyńska, a Google spam fighter who focused on Polish spam and was the face between Polish webmasters and Google, is leaving the Google webspam team and going into a completely different space.
Karolina posted the news in the Google Webmaster Polish Help forum, saying:
Michał Wiciński on Twitter at @MichalWicinski, is taking over her role. He has been with Google, according to his LinkedIn profile, for a year and three months.
Karolina told me on Twitter she will be joining a startup within Google, a company Google acquired in January 2014. It is not spam or search related, so she will be out of the search and spam business for some time.
