Hate-filled fake videos about London are everywhere. We've obtained a recording of a TikToker confessing to secretly filming Londoners in their homes for clicks.

He says it's not political. He just wants to make money from far-right anger.

Read what he says: www.londoncentric.media/p/london-tik...

“Be sceptical of peer-reviewed papers,” @DrJBhattachary says, because editors have conflicts (many are professionals), reviews are anonymous (mostly open), and reviewers are selected by editors (on merit and expertise).

*This* is what journalism is for. Just how was Palantir, a foreign company whose leaders openly call for the elimination of democracy, given ownership of significant segments of UK institutions?

New on FT website:

Downing Street has refused to say whether Sir Keir Starmer knew Palantir was a client of Peter Mandelson’s lobbying firm when they both visited the company in Washington last February — ahead of it winning a £240mn UK government contract.

Some really striking numbers in this new survey showing the flip in European public opinion about America.

But bear in mind this is only Western Europe. In Eastern Europe, it has been harder to take the blinders off peoples' eyes.

Pressure building on govt to come clean about Mandelson's role in bringing US spy-tech firm Palantir into the heart of our NHS.

The fingerprints of Mandelson and his lobbying firm are all over these deals.

Just how much censorship is the Trump Administration doing? This tracker answers that Q. The results are wildly at odds with the Trump regime and conservatives' long-standing accusations of censorship by, uh, "the left", big tech, the EU, Canada, etc.. trumpcensorship.com ht @lewan.bsky.social

So where is the censorship if not in the DSA? It's in the USA.

The Trump administration has censored free speech in 236 actions as of today trumpcensorship.com/

Who would have thought.

That does not mean there aren't reasons to critize the DSA, for example because it does not specify what is harmful content because that's largely left up to the EU member states doi.org/10.1080/1360..., some of whom have stricter rules than others. And that can be problematic.

4. Platforms must file annual systemic risk assessments of their operations and how they might impact democracy, especially with regard to the exercise of fundamental rights of EU citizens. The assessments reveal that Bing, X, Snapchat, and TikTok are all aware of the risks of echo chambers.

3. The DSA mandates data access by independent researchers so they can audit the effects of platform policies on democracy. Surprise, the
effects are not pretty (see e.g. this recent study

2. The DSA mandates that platforms take down illegal content, such as CSAM and scams and offers to buy and sell illegal goods. Meta is earning $7 billion from scam ads each year, suggesting that such consumer protection is essential.

1. The DSA empowers users to object to content moderation decisions made by the platforms. i.e., the DSA protects the public against corporate capriciousness and protects free speech in the EU. Millions of complaints against platforms by users whose content was removed have been upheld.

There have been increasingly shrill accusations against the EU over its digital legislation, based on accusations of "censorship" by defenders of "free speech" -- including, so it appears, the right to peddle an AI app that seemingly produces child sexual abuse material (CSAM).

My more benign half refused to believe this screen snapshot was real. But it checks out. So as usual, whatever is left of my benign view of US folks with "conservative" leanings has been falsified. Nazis. Period.
