It's been a few days since I posted about https://readily.news AKA "open.news", a service which:

1. asks for complete access to your Mastodon/fedi account

2. ingests whatever your account can see via your account and summarizes it using LLMs (seemingly from OpenAI?)

3. sends you a daily, personalized newsletter

It's a particularly bad kind of scraper because it basically hijacks existing community infra to do the scraping for it.

Because accounts' host instances are the actors gathering up all the content there's no way for remote servers to detect which of their followers' accounts have been compromised, nor to block their posts from ending up in the hands of the upstream LLM providers.

We'll probably need admins of affected instances to run a database query to detect and revoke permissions granted to this service via OAuth to limit its access.

I asked the guy who
the guy who appears to be behind it (https://mastodon.social/@librenews
) if he could confirm his affiliation, but he doesn't actually seem to be very active on Mastodon (preferring Bluesky) and so he still hasn't responded.

I'm actually a little surprised at how little reaction there's been to this based on how quickly other scrapers were run off the network, but I get that people are busy.

If you want more details, the specifics of my investigation are in this post:

...and I'd appreciate if others could corroborate my findings.

In case anybody who is more deeply familiar with Mastodon's database internals feels like helping to shut this service down:

I think it would be great to have a command instance admins could run to identify which (if any) of the accounts they host have handed over account access to Readily.news.

It achieves access through the OAuth confirmation dialog shown in the attached screenshot

Screenshot of Mastodon.social's OAuth prompt, through which it is asking whether the user would like to grant Readily extensive permissions to their account, including:

Read and write access to their account, plus its follows, mutes, and blocks.
