[Help needed] How to find sites that allow facebook users to leave comments?

Dear fellow members and experts in Facebook, how do I find sites that allow facebook users to leave comments? Something similar to http://www.soccernet.com

Is there a footprint that I can use to scrape using scrapebox? Thank you for taking your time to answer and Ste Hughes (Please leave my thread alone if you have nothing positive, trolling does not amuse me much but I do respect you for your contritbution on BHW).

These days people want that commenting should be via Facebook so that they can promote themselves on social media and can have some authorized members too.
