I've gotten to the point where if a site displays a popup, I just close the page. If I had the ability to remove that source from all future searches I would.

I've got addons (ublock) and a Javascript bookmarklet that removes all fixed elements, it's fairly effective.

What happens to sites where a fixed element is part of the UI? Confirmation modals etc.

This sounds great! Can you share the code?

[Veen]

You can do just that in Kagi. It lets you boost or block sites from search results.

Why not entering a fake email and move on? It's not like many of them do email validation anyways. Something like [e-mail] will do.

At least let them having to handle junk data.

Or the site's own contact email addresses, if you want to be mischievous without potentially spamming an innocent bystander
