Bluesky says it won't train AI on your posts

It is a promise from Bluesky specifically, not the entire atproto "atmosphere", as they call it. This is ultimately no different than if Twitter promised such a thing, but couldn't stop people from still scraping the site.

> If I can run my own instance can they really promise that?

what? it's Bluesky promising not to do a thing, they're not promising every other entity in the world won't do a thing.

> Other companies could still potentially scrape your Bluesky posts for training. Bluesky’s robots.txt doesn’t exclude crawlers from Google, OpenAI, or others, meaning those companies may crawl Bluesky data. “Bluesky is an open and public social network, much like websites on the Internet itself,” spokesperson Emily Liu tells The Verge. “Just as robots.txt files don’t always prevent outside companies from crawling those sites, the same applies here. That said, we’d like to do our part to ensure that outside orgs respect user consent and are actively discussing within the team on how to achieve this.”

They can't and they fully admit that.

This is certainly aimed at illustrators and artists flocking from X to Bluesky, not people microblogging.

actually our slogan is "the company is a future adversary"

Mastodon can’t promise it either, nor can they prevent it
