Even on sites that have a "Like / Don't like" button, my understanding is that clicking "Don't like" is a form of "engagement", that the suggestion algorithm are going to reward.
Give me a button that says "this article was a scam", and have the publisher give the advertisement money back. Of better yet, give the advertisement money to charity / public services / whatever.
Take a cut of the money being transfered, charge the publishers for being able to get a "clickbait free" green mark if they implement the scheme.
Track the kind of articles that generate the most clickbait-angry comment. Sell back the data.
There might a business model.
