Agree. Better to choose other tools such as seopen toolbar to double check the page rank of the site.
Hello, There is another tool to check fake domains http://www.expireddomainup.com/domain-tools/fake-page-rank-detection.html Or you can do on Google search box cache:domainname dot com, if in cache say the same domain all is right, but if you see another domain, it is a fake domain My 2 cents, Jakomo
