I'm actually working on a project related to stuff like this. Here are some tips:

>You can install the Filmot Title Restorer (using Violent/Tampermonkey) to find privated/deleted video info, but it's quite limited due to API issues for recent (past few years) videos: https://greasyfork.org/en/scripts/430202-filmot-title-restorer

>Alternatively, there are several sites that let you reverse search links, but they probably have the same API limitations:
https://mattw.io/youtube-metadata/
https://filmot.com/
https://quiteaplaylist.com/
https://findyoutubevideo.thetechrobo.ca/

>There are several sites that let you search for unlisted videos (I know unlisted doesn't mean privated/deleted):
https://infinitay.github.io/Unlisted-YouTube-Video-Finder/
https://filmot.com/unlistedSearch
https://unlistedvideos.com/

>Finally, there are archives of deleted videos, but some of them are more like porn sites than anything else:
https://hobune.stream/channels/
>NSFW WARNING:
https://ytboob.com/
https://nudeleted.com/
>MALWARE & NSFW WARNING (might be false positive, it wasn't there before):
https://youncensored.com/

Pic related. Sorry for the lust provoking image, it's the video OP posted.

If anyone knows any other resources, please contribute.
