I heard from some domainname guru videos that they kicked ass their competitors whenever they found any funny things on their domains' whois record. I didn't note much of the details as I thought it was not my war zone. Now I have this client on a niche market which seems to has one competitor dominating the top-10 on every of a bunch of my clients target keywords. The SEO works done on the competitor's domains are very good, a pro job. The only weak point I found is its whois records. All their domains state the Registrant Address/City/Province/State/Postal Code addresses in UK while their country put CN. Phone number is UK and fax number CN, or both CN. Any chance I can take them down, at least for a while, so I can get my client to head the league? Do I just submit this for one per domain? hxxp://reports.internic.net/cgi/registrars/problem-report.cgi What else you will suggest me to do in this battle?
