I too have had a shady competitor double serving by a factor of 6-7 for years. On some keywords has all 7 sites appearing out of the 11 spots available!
All the sites have fake registations from overseas but all are hosted on the same server with the same C block of IP's in the middle east yet presenting themselves as a US based company.
This sector is for a US only consumer software product and this guy also has TONS of complaints for all these sites.
The latest trick is to advertise a fake "customer reviews" site in the top three placements on adwords falsely reviewing ALL his other sites only from a different U.S. based shared server. Funny thing is there's no contact form or any other way for anyone to post a review or contact the site in any way so you would think that alone would be enough proof to google to warrant shutting it down as a "fake arbitrage" site along with the other double serving sites as well.
Please do keep us posted on your progress and I will do the same.
I too feel this type of advertiser hurts the credibility of our sector and is in clear violation of google adwords terms of service.
