A couple of months back I sold one blog in a webmaster forum. While sending the files to the buyer I didnt take off the adsense code in it and informed the buyer to just replace the "pub id" with his. Recently I found that the buyer has posted some content related to "online betting" with my adsense code on it. I have contacted the buyer to remove my ad code and waiting for a reply. However I have changed the settings thru my adsense account which allows to display my adsense ads only in specific sites. (ads will show but clicks will not be recorded - on the sold site). Is my account safe or still I need to contact Adsense?
Just use "allowed site" feature. http://www.adulu.com/showthread.php?t=478&highlight=allowed+site block you previous site and protect your adsense
