real pr

I see countless threads on BHW telling how to check fake pagerank and other ways to do it etc. I wanted to know that when you are looking for High PR domain on GoDaddy auctions how can you then check its PR since it has been parked on GoDaddy's landing page? :confused: What I mean to say is...

The site is: fullaa dot com I used nearly all the tools online to check the PR of the site. They are all returned as VALID. However, the inner pages were all N/A PR. That's weired. I doubt the result. Can anyone tell me How To Prove IT IS A Fake PR. Thanks.
