I’m looking for a plugin or a setting which can add a warning page before redirecting to an external link in any topic, of-course on a self hosted discourse instance. The intention is to prevent phishing attacks.

You can rewrite external links using a theme-component as described by Redirect Page for External URLs - #14 by Johani

Alright. While exploring, I found this plugin GitHub - discourse/discourse-affiliate · GitHub which I guess can be forked and modified for my use-case. What do you say?

That’s even better, as it will affect how the links are saved in the database.

Oh! Does that mean existing topics won’t have this change if I add this plugin now?

We also have this old topic on the matter [image] Preventing malicious linking Feature Continuing the discussion from How Coinbase Uses Discourse to Educate Customers and Improve SEO: If I understand, that warning would be shown to anyone who clicks on a link posted by a TL0 user? What if a TL0 users posts a link to one of our KB articles, or StackOverflow, or Wikipedia? I suppose we could whitelist domains, but it seems like all users are being punished instead of the new user being asked to gain trust. If that was only shown until moderator review, it could work.
