It will help people communicate to Kagi that a search result has significantly changed or has been deleted.
This will improve user experience by removing deleted pages from Kagi search results and making sure that Kagi search results contain more current versions of updated pages.
Every few months, I do a vanity search, searching for my name. I think a lot of people do this.
I found a bunch of pages with my personal information, including my name and home address, lots of stuff.
I worked hard, and got the information removed from the pages.
Months after getting it removed, I did another search on Kagi for my name, just to check again. The pages still came up in the Kagi search results despite having been deleted from the original site, and Kagi's summaries for the pages still included my personal data, despite the actual pages where that information had been visible no longer existing. Kagi itself is now the site where people can find my personal information, because the pages containing my personal information has been removed from those pages.
I'd love a way for Kagi to allow me to mark pages as outdated/deleted, so that Kagi can know to reindex a page and see if it should be looked at again or removed from the index.
