My adsense account is over 4 years old. I installed statcounter a week ago in order to get a better understanding of my traffic. Yesterday I noticed in my 'Exit links>visitor paths' that someone from Bulgaria came to my site via search and clicked on Google ads.. 10 times, 1 every minute or so. My adsense stats however didn't record all of those clicks. The question is, should I let this pass by or would I be called paranoid to let google know about this or should I ban the IP address entirely? I'm hoping my account won't be messed up just for a few clicks?
