Facebook has recently started inserting advertisements into my feed, where they are disguised as posts from friends and organizations I follow. My ad blocker seems unable to recognize these as advertisements, but can be configured to block specific markup. Unfortunately, as near as I can tell, Facebook has been aggressive in obfuscating the markup for such posts, making them hard to distinguish from real posts.
Is there distinctive markup in Facebook's new stealth ads that can be used to identify them. Are then ad blockers that can do this?
