Under every search result, it includes a count of how many results got blocked if any are found, with a link to fully disable personalization.
My proposed feature would be to also have a link to show the exact results that got blocked.
This provides a quick, easy way to see if a domain that was blocked might actually be useful and allows the user to quickly decide whether it should be kept blocked or changed to unblocked.
Steps of workflow:
A user named User searches something like "big trucks 🛻"
User notices that there are 9 blocked results.
User clicks on it and the blocked results show up underneath.
User inspects each result and decides whether any of them warrants an unblock.
One of the results is from "kindabigtrucks.com" and User opens it and finds it relevant.
User unblocks "kindabigtrucks.com" and the next relevant search they make will show it.
User closes the blocked results section and continue to the main search results.
