Back in December 2010 the front page of my site was ripped off and hosted on another domain. I noticed it because they kept my tracking code in the HTML so I could see the domain it was coming from - plus thousands of visitors came in a very short space of time.
Less than a month later, my site was penalised. This was something that took me nearly 5 months and 6 reconsideration requests to rectify. At the time I swore the two things were linked.
Now today I have got about 5 visitors per second arriving from a domain (with words in the same niche) which is iframing my home page. There is nothing but the iframe, and a hell of a lot of traffic (presumably bought traffic). Do I have a lot to fear here, SEO wise? I wish I could preemtively tell Google "IT'S NOT ME!"
I have sent a cease and desist to the hosts as a bare minimum but I don't know how long they will take to remove the content, if at all.
Given past history, this really unnerves me, for the fact that in both instances there appeared to be no direct benefit to the perpetrators, so something shady is obviously going on.
Anyone on the 'dark side' know if this is a known method of harming a site?
