In which I put my head in the lion’s jaws and write 2700 words about privacy and full-text search on #mastodon: https://www.tbray.org/ongoing/When/202x/2022/12/30/Mastodon-Privacy-and-Search
Not of the admins block it with robots.txt
@timbray @codeyarns not so fast! If my post federates to another instance that doesn't block search with robots.txt, then it 's still likely to wind up in a search engine (even if I've selected the "opt out of search engines" option). I've even found federated versions of deleted posts via search engines.
As you say, Mastodon's privacy story has problems.
The frustrating thing is, local-only toots help a lot here ... but they've been blocked from the main branch since 2017
If your post carries clear licensing restrictions, there's then a legal club available to beat anyone who misuses it. That's my piece's central point.
