If you feed somebody's posts into your shitty LLM without an explicit and reversible opt-in, you are violating the consent of fedi users.
This "Zeitgeist" app not only violates consent, but it also doesn't have a centralized ActivityPub identity that can be blocked or defederated.
https://zeitgeist.blue is a multi-social-network app that summarizes your feed for the last 24 hours to let you catch up with doomscrolling. Now with support for Mastodon!
