I'n not an expert on this but I have done some research. This particular site was registered on
30 January 2012, just a week before the last PR update on 6 February.
It is apparently possible to set up a redirect from an existing PR4 site to another one (and so pass on that PR) and then remove it immediately after the update. In this way the new site allegedly will display a PR4 and a "fake page rank" checker will not reveal the redirect.
One suggested way of verifying whether or not the PR is genuine is to use Open Site Explorer and look at the domain authority given and the links. However, the last update of OSE was February 28 and by that time the site hadn't been indexed (by OSE) and information will not be available until the next one on 28 April. Similarly, the fake PR would continue to be displayed until the next PR update.
Whichever way you look at it, it is difficult to imagine how a site can legitimately be given a PR4 within one week of registration.
