I’ve worked in Trust & Safety long enough to know this: a platform’s culture is not what its brand deck says, it’s what its enforcement does. Every policy choice, shows customers who a company is. tgthorley.com/blog/f/trust...

First community labeler taking actions on atproto using @roost.tools’s Osprey. entire Ozone and Osprey stack running on a $50/m OVH machine, with up to seven days of full firehose backfill for investigating patterns and exploring the network.

As we see images of violence and brutality in our streets, Moderators can burnout fast when it has impact to their communities and their lives. Making sure we are looking after them and their wellbeing is a responsibility we should not take lightly. tgthorley.com/blog/f/trust...

Bad Bunny condemns ICE during his #GRAMMYs speech for Best Música Urbana Album: “Before I say thanks to god, I’m going to say, ICE out. We’re not savages, we’re not animals, we are humans and we are Americans.”

Catherine O’Hara was a genius, a light, and a joy-maker. What a loss to the world.

Definitions of terrorism are aways debated… but they generally contain: - Political Motivation - Violence - Intent to intimidate a population - Targetting civilians I wonder if there are any examples that come to mind…

Every moment now, every day, more & more Americans realize they can no longer trust anything the federal government says. The blatant propaganda and lies about a legal observer they shot in cold blood will bring a new swell. To those of you who were not here before: Welcome. We need you.

Do not store your Bitlocker encryption keys on Microsoft's servers if your threat model includes governments or law enforcement. As this article points out, this is the result of a design choice Microsoft made. It didn't have to be this way. www.forbes.com/sites/thomas...

As someone who at times watch execution videos professionally; don't watch execution videos if you can avoid it.

🧵“How do seemingly ordinary people become agents of state murder?” This is one of the guiding questions I ask students in my graduate class on genocide/state violence. With recent events, it is a question many Americans are asking. I do not have a definitive answer, but here is a reading list: 1/

for sure, but this obviously goes well beyond the ICE murderer who pulled the trigger. there is culpability all the way to the white house. and the culture of elite impunity in this country has to end now.

What is happening on the streets of the US with “Law Enforcement” agents killing people is disgusting, horrific and outrageous. I don’t have a take. I don’t have words. I don’t have advice for how to fight back. I am just grieving.

Many things one can say about this outrage, but as a terrorism researcher, I want to say to current and future students that this is one reason you should never rely on government databases to tell you who or what is a 'terrorist', domestic or otherwise.

For remote teams working in T&S hiring is one of the most important (and expensive things we do, good decisions pay massive dividends, mistakes cause massive headaches (for both employer and employee!) - and I've made plenty of both! tgthorley.com/blog/f/trust...

🇮🇷 NEW: Real-time monitoring shows Iran is experiencing a nationwide internet blackout, following digital censorship linked to escalating protests in Tehran and other cities.

WTF … this is basically the equivalent of we arent playing in the UN… I think the UN should look for new accommodation before Trump renames the UN HQ in New York…

I've been thinking about #remoteworking and how to build teams and culture while working remotely, especially in #Trust&Safety - The proximity of in-person work environments is very often just making it easier for us to navigate ambiguity. tgthorley.com/blog/f/trust...

Check out our most recent episode to find some inspiration going into 2026.

#Merry #Christmas everyone. 2025 has been hard… almost from day one to day 365 for some many reasons. But I still feel optimistic about the future. I still feel that we can turn around the insanity and get back to treating people humanly, with dignity and respect. 2026 needs to be about community.

And a big welcome to the inaugural Technical Design Committee. These are the community leaders shepherding @roost.tools projects! @hailey.at @tpepper.bsky.social @tgthorley.bsky.social Naren Koneru Dr Rebecca Portnoff Sam Tozier Shu Lei Vinay Rao

Also joining the TDC is @tgthorley.bsky.social, who joins with a background in user safety and countering harassment & malware detection, and eradicating CSAM and TVEC on GitHub. Prior to GitHub, Tom served at @gifct.bsky.social and spent 10 yrs at the British signals intelligence agency, GCHQ

Does anyone else get soooo car sick in the back of Teslas? In addition to wanting to boycott the company, I want to get out of my #Uber or #Lyft not feeling like death. Please Uber - give me the option to filter out these awful vehicles.

We're excited to announce the result of months of collaboration with OpenAI, gpt-oss-safeguard. This reasoning model is designed for safety workflows where you bring your OWN policy and definitions of safety, and it explains each decision it makes. Learn more here: roost.tools/blog/a-new-m...

Today at #githubuniverse I spoke about how we are keeping developers safe using a combination of expert safety professionals, advanced Agentic AI workflow and community prevention and culture building efforts.

So people demand "AI" sycophancy, refuse to interact w/ *less* sycophantic "AI", & then get increasingly ill-disposed toward interacting w/ other human beings, preferring, again, an "AI" system that is actively locking them into a loop of skills dependency, bias confirmation, & hostility. SEEMS BAD

As the Trump administration continues its crackdown, millions across the US are expected to hit the streets for this weekend's "No Kings" protest. If that includes you or your loved ones, here's a 🧵 of guides to follow to protest safely in the age of surveillance. wrd.cm/4lEVQu9

#BlueskyArtShow #Vertical #Caturday It’s a two twofer this week!

I spent much of the day with #AmericaOnTech at @nbcuniversal.com today talking about the future of work and how AI impacts that. My takeaway was that employers want and need diverse perspectives and so programs like AOT are critical. Also …

Jane Goodall understood better than most the impact humans have had on the planet. Having witnessed so much environmental deterioration during her lifetime, she was as much an activist as a scientist. Read our piece from 2024 on the legendary primatologist. 💚

#BlueSkyArtShow #TheRoad in Cirencester on my way to Bath many years ago. It was so dark driving these Cotswold lanes and I couldn’t resist pulling over to take shots of the light trails.

Tonight at #HollywoodBowl was an amazing tribute to Minnie Riperton with Aloe Blacc, George Benson and Stevie Wonder… such a privilege just to be present.

Today is 9/11 —a day that holds deep personal meaning for me. It’s one of the reasons I entered Intel work, a long career countering terrorism, and ultimately led me to the role I’m in today. That moment shaped my sense of purpose: to help protect people and make the internet a safer place.

GitHub is the home for ALL developers. I spoken to quite a few Syrian developers who had been affected by the trade restrictions and know the positive impact that this change will have. Thanks for making the world a more collaborative place - one pull request at a time github.blog/company/gith...
