I started seeing this weird ad appearing on my site this weekend. I am pretty sure it for a USB connector. It looks like a flash ad and I cannot figure out a way to see what the domain is to block it. I cannot even click on the ad...when I do nothing happens.
Given your recent history with AdSense TOS violation I'm really surprised you'd actually attempt to click on your own ads? Why wouldn't you just contact them? You are a big enough publisher that you'll get a response.
