I accepted adverts for the index page of two of my sites about 4 weeks ago, at the last google update both sites dropped by 1 PR. I wonder if this was a coincidence and the PR loss was due to another factor or Google just does not like you linking to gambling site.
But the site in question has a good PR of its own before I link to it.
