I've been tracking the spread of nonconsensual deepfakes on X for more than two years. Here's a timeline of how Musk's leadership allowed the practice to flourish from a once-underground market to a viral trend, with little recourse for victims or legal enforcement.

Nonconsensual deepfakes on X are nothing new, but now it's built into the platform.

Lots of stunners here: 1. calling a sociopathic narcissistic idiot a "genius". 2. tacitly linking a fabricated hate campaign against Somali-Americans to the equally fabricated hate campaign against Jews by the Nazis. 3. doing it in broad daylight.

Curtis Yarvin, JD Vance’s friend & ideological influence, ended 2025 by claiming “only Hitler spoke the truth” about “too many subjects” & “Hitler was a genius.”

Extremism isn’t fringe on the right. Once marginal online extremists like Yarvin are influential at the highest levels of government.

Indeed. But it's not just Putin. It is also Trump, Musk, and the other plutocrats. I don't think this is about Russia v. EU, it's about plutocrats and oligarchs v. democracy.

Oh look, Jonathan Turley mentioned me in one of his “angry old man on porch” pieces again. He just can’t help himself. He does it a few times a year, as I explain below. You’d think a preeminent legal scholar wouldn’t concern himself with a 36yo mom but NOPE

Let’s talk about something not many people are chatting about and what’s actually happening right now.

You might wonder why Imran Ahmed and the Center for Countering Digital Hate (CCDH) suddenly became targets of the U.S. government. The honest answer is that their research hit where it hurt.

Die Stellungnahme der EU-Kommission zu den Trumps Anti-DSA-Sanktionen lenkt vom zentralen Punkt ab: Seit Monaten setzt die EU-Kommission das EU-Digitalrecht nur mutlos um. Die Strafhöhen sind zu niedrig, die Verfahren zu langsam, Sanktionen ja werden nicht verhängt. Das muss sich jetzt ändern!

Yoel Roth @yoyoel.com · 9d

A small (personal) example of this book’s intellectual dishonesty:

My father-in-law is reading In Covid’s Wake, and excitedly told me he found a passage where I’m quoted. The quote in question is me saying the FBI worked to censor speech on social media.

Huh? When did I say that?!

A passage from the book In Covid’s Wake, with a highlighted sentence reading: “Yoel Roth, the former head of trust and safety at Twitter, states that "the FBI went beyond strategic information sharing and made direct moderation demands," including demands involving domestic speech.”

The EU lawmaker who was in charge of digital affairs during 🇪🇺President von der Leyen's first term has been banned from entering the United States, because the 🇺🇸 tech giants and government don't like the EU's tech laws.

Want to see how they lie? I published this last week: Matt and his assistant Andrew Lowenthal cutting emails in half and lying about what they said to spin up the antivax rage machine. The Twitter Files were a propaganda campaign. And here we are now.

The US State Department is now going to be deporting people and/or revoking visas over Benz, Taibbi, and Shellenberger’s “censorship industrial complex” hoax.
