This is how adblockers work (sort of).

We could probably leverage the same tech used for adblockers to make UI blockers, which maintain lists of "bad" UI and remove their tags and scripts.

Of course, I find it easier to just not use those websites.

In fact you can just right click an element and block it with most desktop ad-blockers.
