is that posibble to fake pagerank?

After wrote about "why i need pagerank for my site", another question pop-up.
is that possible to fake pagerank? and the answer is yes.

From that i found, with some blackhat trick is very possible to do that. some people want their site/blog have reputation, but just want sell domain with high prize. the victim usually newbie that want to start online business.
This day, many site that offering pagerank checking. But the simple ways, just type "info:domainname" in google search. A fake pagerank usualy dont have many backlink, a site with high Pagerank have many backlink.

How it`s works?
With little cheating script, usually they call another header from another site with high Pagerank.

Google always update their system and their rules seem more strict in everytime. I don`t know if those blackhat way until when those cheating script can be use.

In domain auction, they offer many expired domains. If you are lucky, you can have a cheap domain with high pagerank. But remember maybe some of them have fake pagerank. The auction company didn`t have any resposbilty if you buy this.Some third party site, sometime offer more filter than company does. With advance search it`s more easy to eliminated fake pagerank.
