It’s very annoying to click on a link that takes us to an article containing a paywall. Unfortunately we never know it in advance. We generate traffic for the sites, we expose ourselves to advertising and we can’t read the article, it’s a waste of time. It would be nice to have some kind of add-on for browsers that would detect if the links refer to a paid article, and that would warn us before clicking on it by adding via CSS a kind of small symbol in front of the link.

For example: 🛑 https://link.tld

We could imagine that when a user goes to a web page of an article that contains a paywall, he could click on a button of the add-on to report the article, and thus enrich a collectively built database.
