What We Can Learn from the First Digital Services Act Out-of-Court Dispute Settlements? | TechPolicy.Press Ramsha Jahangir spoke to two experts to unpack what the early wave of disputes tells us about how the out-of-court system is working under the DSA.

Under Article 21 of the DSA, out-of-court bodies review moderation disputes. One such body, Appeals Centre Europe, has released its first transparency report.
@ramshajahangir.bsky.social spoke with Thomas Hughes and Paddy Leerssen about what these early findings suggest.

I think they're adding a /?tl=[language code] suffix to all their research results, so the translation persists even when you continue to the source page. It seems to have a knack for turning all my English result Dutch and all my Dutch results English - truly an enshittification masterstroke.

Not content just ruining their own product, Google Search is now auto-translating all my <site:reddit.com> queries. One of the few remaining use cases for Search and they can't resist screwing with it.

In today's Briefing: I found 114 ads for AI nudifiers on Meta.

The copy of the ads included the word "undress," which isn't a sophisticated term to watch out for.

As always, I flagged these ads to Meta, which took them down. Google also took down a related app.

Thanks Rachel!

Calling it a 'publication' may be premature since it's still just a self-published PDF. But i'm glad it's out there and being read, hopefully peer review will be as kind🀞

Thanks David! And a long time coming--this is the (by now almost unrecognisably altered) continuation of the CPEM research I shared with you last summer. The topic has only become more relevant since then, I think.

What I found is that corporate structure at X and Meta are distinctly oligarchic. We may be at the cusp of a great divergence between oligarchic and market firms, and intensifying conflict between ownership and management.

Still in draft so comments welcome! πŸ™

To answer these questions, I spent a lot of time this semester digging through SEC disclosures and other public records -- and reading memoirs by former platform executives on their experiences with ownership influence.

From Murdoch to Musk: Social media ownership and the political economy of platform content governance

The question is simple: who owns the major social media companies, and how do these owners influence content governance outcomes?

So... I'm not saying you should sue any platforms under the DSA. But if you *did* want to do that, you'd definitely want to look at this article from @pjleerssen.bsky.social, Iris Toepoel, Anna van Duin, and @jvh.bsky.social

It's basically a tactical guide.

SPUI25: Hoe kunnen we het recht inzetten om mensen minder te laten vliegen? Luchtvaart is een vervuilende bezigheid: Iemand die van Lissabon naar New York vliegt en terug, veroorzaakt ongeveer evenveel uitstoot als een gemiddelde EU-burger doet door zijn huis een heel jaar te verwarmen. Sinds 1992 maakt de EU wetten en beleid om de uitstoot van de luchtvaart aan te pakken, maar ondertussen heeft de uitstoot door de luchtvaart recordhoogtes bereikt. Hoe kunnen we dit inperken?

Coming soon πŸ“£: @yannickvdberg.bsky.social in SPUI25 over het recht gebruiken om mensen minder te laten vliegen ✈️ Meld je aan voor het event op 13 juni https://bit.ly/459lUJw

Yesterday, for the first time, I presented findings from a new empirical project. The question is simple: who owns social media?

I'm leaving the AoIR symposium in Bremen more inspired than ever to pursue this topic. Many thanks to the organisers at @zemki.bsky.social!

Yeah I had a spell last year where I got ahead of myself and started talking up a grant application about the political economy of expertise. But I didn't get the money and never found time to really pursue it - on to other things now.

Rachel's paper is great!

WAITRESS: please keep your voices down, this is a family restaurant.

WALTER: Oh please dear! For your information: the Supreme Court roundly rejected prior restraint!

DUDE: C'mon Walter, this is not a First Amendment thing, man.

I'm no expert in programming, but as a prolific fat fingerer I concur.

Then again, given how much programmers use GenAI these days, maybe that's just as likely a source of catastrophic, easily-overlooked errors these days?

Instagram 'Error' Turned Reels Into Neverending Scroll of Murder, Gore, and Violence β€œToday’s algorithm showed me around 70 murders, 100+ accidents, and around 115 violence videos, is anyone on Instagram noticing it?”

The 'Instagore' story from last week is absolutely nuts and really flew under the radar.

No clear explanation either. Theories I've seen:
- deliberate sabotage, e.g. from a disgruntled employee?
- coding error, e.g. inverting ranking scores to show lowest first?
