Crazy FaceBook Fanpage / Pages Pagerank?

What is up with the latest Google pagerank?

I created a bunch of facebook pages only about a month ago and have been using a number of 'get likes' sites on them.

Average number of fans / page is about 500 up to 1000...

But heres the crazy thing..

They all have a PR of 3 - 4?

It makes no sense??

Anyone else find their Facebook pages have massive fast PR jumps?

I mean 1 mth old page with a PR4 is a record for me.

Check out you FB pages and see if yours are raking ok.

PS: Anyone with info how this is happening would be welcome.

i have a Facebook page that is number 1 for a keyword and gets 1000 searches a month from google.so yes it does happen.

Wow awesome work, I dont see too many FB pages in my SERP's, I was more curious how the PR got so high so fast.

Maybe each like = a unique page backlink in the Google algo.
