As a tip, if you just need to read the content from the search result then they seem to be commonly available in the wayback machine:

https://web.archive.org

It does mean you need to cut-n-paste the Reddit url there, but it's been working for the content I needed to look into yesterday.

But are they serving a 410 (or other eeror code?) ? Looks like no to me. The algo may not respond as fast

Google knows if you follow a search result, then quickly go back to the search page.

Which has always been the case for anything tagged NSFW, or anything at all in a mobile browser. Every piece of SEO advice says this will get downranked from Google, but Reddit demonstrates this isn't true.
