Can you show me proof besides from the screenshot. eg. what tool you used to check PR? Or did someone sell you the site, claiming it was PR7? I am pretty sure it is a PR0
I just moved it to godaddy when it started saying it is PR N/A ,for some reason ,You could use Fastpagerank.com so you could make sure,It is more than a 7 years old PR7 Domain and I'm sure that it is.
Fastpagerank.com? They think its fake: Not sure how you missed the bit where it says Fake/Real Indicator. I would agree with them. I mean, the site isn't even indexed by Google. Sounds like you have been duped by the seller.
You need to be logged in to see it. Whoever sold you this domain name, I would ask for my money back. I wouldn't be surprised if they 301 redirected the site to a high PR website to give it a temporary PR boost before selling it to you, knowing that the PR would plummet like a rock. I would also let everyone know that they are a scammer. Good luck.
