I installed the plug in on my wordpress blog and it appears the plug in crawled several blog posts. Unfortunately, each of those blog posts has an adsense ad running on them and the plug in "clicked" these ads. This activity cause an extremely high # of invalid clicks to my adsense account and has now placed my business in jeopardy of being banned from the Google adsense program. I've now uninstalled the plug in and the "clicks" have stopped. Dont' use this if you are running PPC ads on your site as it will cause your account to have invalid, and high, click activity.
