While looking at my Adsense report today, I noticed a domain in there that isn't ours.
I've been running our site since 1997. Today I noticed an unknown site in our reports and when I went to it, it has our site in a full page iframe, that is, there are no bars on top. Its sole apparent reason to exist appears to be displaying our site with a different URL.
Currently all the ads are still ours, internal links still point to us, but I'm concerned that it will begin to engage in clickjacking, damage our standing with Google, or damage the name we've built in the news world.
The site that is hijacking us is literally our sitename with the word blog appended to it and it appears to have been registered yesterday, Dec. 2nd, 2013. I've already filed a complaint with the domain registrar.
Will this cause us any issues with Google like duplicate content? Or is the fact that it's in an iframe save us from that?
