Reviewing my referrer logs again after the recent hotlinking issues I noticed another new referrer cropping up planetwordpress.com. Taking a look at the site in question it seems to be a WordPress install aggregating the content from a lot of WordPress blogs including most of those pulled into the official and unofficial WordPress planets (planet.wordpress.org and planetwordpress.planetozh.com respectively).
The new planetwordpress.com site seems to have the sole purpose of generating money from adsense clicks based on other content which I’m sure goes against the licence I have my content under (CC Attribution-NonCommercial-ShareAlike 2.0) and as such I have contacted Google to complain about the sites participation in the adsense program. Searching Google for mentions of planetwordpress.com it seems like I am not the only person to notice there content being stolen.
