(sorry for the double post but I came across something unexpected)
Going to add the G+1 I looked at their policy at https://developers.google.com/+/plugins/buttons-policy and found that:
"Users can express their interest in a Publisher or its website by clicking the +1 button, and can share content from the Publisher's website to Google+. "
Can share content, does that sound like copy the sites content over. Am I misreading?
