Headed to London with lots of FOSDEM-attendee feedback on what's needed to make online safety easier for independent and decentralized communities (and all the @roost.tools swag I stole from @cassidyjames.com...)

Digital sovereignty and resilience conversations over the last few years have focused on infrastructure — compute, cloud capabilities — but it’s time to add safety to that list of critical digital infrastructure. Great overview on what this means from @aditya.myatproto.social
European social media alternatives need more than EU hosting. They require decentralized architecture, robust safety mechanisms, public funding, and business models beyond surveillance. Read more in @aditya.myatproto.social latest: openfuture.eu/blog/what-is...
What is a “European Alternative” to X? – Open Future
European alternatives to Big Tech platforms must go beyond sovereignty—they need decentralized models, robust safety, and public funding.

If you're a software versioning nerd, you know your first 1.0.0 is a big deal. 1.0 means a stable project ready to go, and that's been proven by the multiple users who've rolled out Osprey as their real-time investigation tool.
A massive thank you and congratulations to the Osprey contributors!

Unfortunately I know nothing about chicken development, so if @roost.tools were a dog, we'd still have oversized puppy feet. AND YET we put free online safety tools out in the world, users are running them in production, and there's a community growing around them. A strong start for 11 months in!
my GOODNESS it has been a busy year! @roost.tools is still under 1 year old and we're pretty proud of what we've accomplished in 2025. Read on for details ✨

When the core primitives of trust and safety infrastructure are open source, everyone gets to experiment, tweak, and make it work for them, like @hailey.at just did.

Since joining @roost.tools, I've had some fun conversations about, "How does this #opensource thing work?"
There's so much #trustandsafety has to gain from having open source infrastructure as its core. Happy to answer all the questions about how this works (while I peel Thanksgiving vegetables..)!

ROOST.tools has been building against the DIRE framework for online trust and safety: Detection, Investigation, Review and Enforcement. ROOST's Coop and Osprey tools address I, R, and E, but Detection is best addressed by classification models.

Excited to announce here at the @parispeaceforum.bsky.social that, after months of joint technical work together, OpenAI will open source through ROOST one of its main internal models that handles detection and moderation. This will allow anyone or any company to use, test, and study the model.

The more I read about the challenges of effective CSAM reports, the more it reminds me of where security vulnerability reporting was pre-CVE.
The CVE system isn’t perfect, but it’s nothing short of amazing how a group of people came together and created what would become an industry-wide standard.

there's some more to do here in the repo to get it where i want, but will probably write a leaflet soon on making moderation work for people that are not Bluesky PBC. hoping that this will be a good step in that direction.
