wrong thread...
But to answer your question....
This is the real PR of the site. It is how it got that PR that you need to watch out for.
It got the PR by hacking into other sites with high PR and putting a link into that site on their index page. The link is hidden using CSS to make it 0 pixels. Google gives the PR, but the relevance of the link is crap. Also when the owner figures out they are hacked they will remove this link and suddenly the side will go from PR6 to PR3 or less. And then having a trade with this person will not make sense...
Pretend they gave you that PR6 and you offered them back:
PR3 + PR2 + PR0 + PR0 + PR0
When they snap back to PR3 you are going to have a very lopsided trade. Also the site has no textual content. So it can't pass much relevance to you. Finally the link is a footer link so it is crap anyway...

The exploit used on most of the sites was the zero day that just got patched in Cpanel.
This user has had a lot of PR6 and PR5 sites drop to PR3 to PR0 in the last 2 weeks... Which means his victims are complaining to Google and as Google sees what is going on they are removing the PR juice.
Worth every cent.
