For example, I'd be happy if any link to a paywall site is replaced by a text indicating this is filtered. I don't want to see any paywall site results in Google search, or links in Google news... etc.
Appreciate any pointers.
It basically looked for all the "a" elements in the DOM and:
1. Set the href to call a JavaScript void
2. Set the element style's text-decoration to none
3. Set the element style's background color to #f3f315
