Social network Bluesky recently published a proposal on GitHub outlining new options it could give users to indicate whether they want their posts and data to be scraped for things like generative AI training and public archiving.CEO Jay Graber discussed the proposal earlier this week, while on-stage at South by Southwest, but it attracted fresh attention on Friday night, after she posted about it on Bluesky. Some users reacted with alarm to the companys plans, which they saw as a reversal of Blueskys previous insistence that it wont sell user data to advertisers and wont train AI on user posts.Oh, hell no! the user Sketchette wrote. The beauty of this platform was the NOT sharing of information. Especially gen AI. Dont you cave now.Graber replied that generative AI companies are already scraping public data from across the web, including from Bluesky, since everything on Bluesky is public like a website is public. So she said Bluesky is trying to create a new standard to govern that scraping, similar to the robots.txt file that websites use to communicate their permissions to web crawlers.Debates about AI training and copyright have dragged robots.txt into the spotlight, among other things highlighting the fact that its not legally enforceable. Bluesky frames its proposed standard as one that would have a similar mechanism and expectations, providing a machine-readable format, which good actors are expected to abide, and does carry ethical weight, but is not legally enforceable.Under the proposal, users of the Bluesky app, or other apps that use the underlying ATProtocol, could go into their settings and allow or disallow the usage of their Bluesky data across four categories: generative AI, protocol bridging (i.e., connecting different social ecosystems), bulk datasets, and web archiving (such as the Internet Archives Wayback Machine).If a user indicates that they dont want their data used to train generative AI, the proposal says, Companies and research teams building AI training sets are expected to respect this intent when they see it, either when scraping websites, or doing bulk transfers using the protocol itself.Molly White, who writes the Citation Needed newsletter and Web3 is Going Just Great blog, described this as a good proposal, and said it was weird to see people flaming BlueSky for it, since its not so much welcoming in AI scraping but rather trying to add a consent signal to allow users to communicate preferences for the scraping that is already happening.I think the weakness with this and [Creative Commons] similar proposal for preference signals is that they rely on scrapers to respect these signals out of some desire to be good actors, White continued. Weve already seen some of these companies blow right past robots.txt or pirate material to scrape.
