I thought the @sarahkendzior.bsky.social suspension was an interestingly nontrivial moderation scenario. I wrote up a little case study/explainer on how it might have been handled on Mastodon. Probably only for people who care about moderation nitty-gritty.

Dear World: Now is a good time to get off social media that’s becoming any combination of “less useful”, “less safe”, or “less fun”. I’ve been on Mastodon for 3 years and am convinced that right now, in late 2025, it’s the best place to go. Come join me. Here’s why.

Hmm: Ms Kendzior said: “the last things I posted were excerpts from my substack newsletter articles”. From her most recent “When I loved New York”: “for example, arrest war criminal Benjamin Netanyahu”. I wonder if that phrase gets you banned? sarahkendzior.substack.com/p/when-i-lov...

Over the weekend I ripped Google search out of my blog because it doesn’t work very well any more and replaced with PageFind, which is really pretty cool. Details: https://www.tbray.org/ongoing/When/202x/2025/11/01/Blog-Search-Pagefind

Does Bluesky Social PBC publish any financial disclosures? I'm super interested in the economics of post-Twitter decentralized social media. (I'm similarly poking around the Fediverse and OMG it's complicated.)

Last week I gave a talk at the IPTC’s “Photo Metadata Conference”. Here’s a blog-ified version, with lots of juicy digging into exactly what works and what’s broken in C2PA in 2025. Also strong opinions about provenance. And a link to the YouTube recording […]

This Thu is the “IPTC Photo Metadata Conference 2025”, a free Zoom event open to all. I’m a speaker ( on #C2PA). Looks like it should be interesting for anyone interested in the tangle of issues about media provenance, #genAI, publishing workflow, social media, and so on.

Due to my persistent yelling about C2PA and provenance, I’ve been invited to speak at the IPTC Photo Metadata Conference 2025: iptc.org/events/photo-metadata - September 18th.

It’s a free Zoom thing, so if you’re interested in this stuff, sign up and drop by.

I'm still digging into #c2pa and have a problem: I don’t have a camera that is equipped. If anyone reading this has such a camera, I’d sure appreciate it if they could take a picture of, well, anything, with embedded C2PA, and shoot me a copy. Should the work ever go public, I’d provide […]

In which I argue that arguments about whether #genai is useful or not are the wrong arguments. The important issues are what it’s for and what it costs.

Having very unkind feelings about the people pushing it.
