Cr*p site PR2 in big G - how?

Hi all,
Just a quick question, maybe some of you have ideas at how this could happen...
In around March this year I created a movies site with MoviePress and, using BHCB and CPARedirector, both tied to a URL rotator, I tried to monetise by incenting non-incent offers across many networks.
I used YT to drive traffic to "supposed" full versions of movies.
The content was some images of each movie, and direct copy and paste of IMDB info (no spinning, no original content, nothing).
To top it all, because of the BH methodology used, I created no Privacy page, no TOS page and no Contact page.
And yet, 6 months on, I check the PageRank for this site, which I long since abandoned (so now the content, as well as rubbish and unoriginal, is stagnant), and find it is PR2!!!
Does anyone have any idea why this could be? Why would the big G give a PR2 to a site which is so obviously unoriginal, and with none of the required "legalese" included?
Any hints on what may have happened would be welcome - I'm sorry, but since this is the first site I've ever achieved more than a PR0 on, I cannot post its URL, but it's pretty much exactly the same as all the other content-locked moviesitepress sites out there.

I registered a domain regarding a really niche practice, wrote three paragraphs about it, and had a second page full of videos. The homepage gained PR2 and the videos page PR3 after TWO WEEKS. (It was well-timed for the PR update )

I've also had a Wordpress install with a single post on it become PR2 after a few months of neglect. Google does some unexplainable things.

its quite possible that someone stumbled across it and gave a decent link. It does happen

Have thanked you both for your comments - I suppose some site linking to mine could be the answer, it just bugs me that sites I've gone all out to make an effort on have got nowhere, and this stupid site gets the PR2!!!

As an aside, to Traffics Pain - I'm in same country as you, down south - hit me up if you'd like to get in touch.

we all get them.... I had a PR3 with loads of PR inner pages, even a PR4 inner page... no link building no nothing!! probably lose it on the next update, but the big G does make mistakes from time to time!! I have had a couple now!
