domains with page rank

hey, where i can buy a from a auction/deleted domain names with page rank above 2 ?

It's not so hard finding deleted domains with pagerank above PR2, but there are a few a day. I wonted to buy some but there was a thing confusing me. If you test any of that domains with a pr tool, fake pr checker, across multiple data centers... everything looks ok, and legit, but when you search for it in google or any other search engine there are no results, like its banned or something, or maybe when the domain is deleted is automatically deindexed?
