I'm aware of the fact that Page Rank is pretty meaningless these days, although it can be used to command a higher price for advertising and backlinking.
I've been doing some tests on PR pushing on a couple of my older domains, and came across a strange result.
I have a domain that only has 5 backlinks. They are mostly PR0 pages linking in, with the exception of a forum post from wordpress.org - which doesn't show the PR. But it's probably 0, since it's just on a forum page.
The strange thing is that my site has gone up to a PR5
Hmm...only a couple of worthless backlinks and Google thinks it's a PR5
