pretty silly:the info that is used/read and displayed by the script relates to The Web Page URL ONLY not users/visitors.
page A has a link to page B - that is it!
Page A likes Page B -> Page B likes Page A
so we are back to the original line:
"Script does not collect any personal data..."
i can only add/change it to "Script does not collect any personal data... whatsoever" unless you feel that URL is a person...
