On TikTok, YouTube, X, and everywhere, ‘views’ are lies You might think a “view” means you watched something. You’d be wrong.

This indeed. www.theverge.com/social/63981...

This is a bit embarrassing, Germany’s Goethe Institut created a cartoon (and a video) story about my news literacy work. I am not sure how this would be helpful to anyone, but here it is. youtu.be/FOQ6SAe4jGs

Misleading: Crying cameraperson video is unrelated to recent Trump-Zelenskyy spat | annie lab The footage comes from a 9-year-old reality TV show in Turkey. It has nothing to do with the fiery exchange at the White House between the two leaders.

Yes, the cameraperson was genuinely in tears, but the footage is nine years old. It has nothing to do with the recent meeting between Zelenskyy and Trump. annielab.org/2025/03/13/m...

False: Arrested man’s face swapped with MIRROR star Keung To in manipulated image | annie lab In the original news photo, the man appears to have thick eyebrows and facial hair. The incident has nothing to do with the popular boy band singer.

Does the arrested man look like Hong Kong Cantopop heartthrob Keung To? Nope, the image shows a typical face swap manipulation. annielab.org/2025/03/12/f...

Zuckerberg’s Meta considered sharing user data with China, whistleblower alleges Meta went to extreme lengths, including developing a censorship system, in a failed attempt to bring Facebook to millions of internet users in China, according to a whistleblower complaint.

[Quote]“In exchange for the ability to establish operations in China, FB will agree to grant the Chinese government access to Chinese users’ data — including Hongkongese users’ data,” one privacy policy staffer wrote. [Unquote] www.washingtonpost.com/technology/2...

Executive Summary
A pro-Russia content aggregation network, Pravda, appears to be set up to flood large-language models with pro-Kremlin content, The American Sunlight Project has found. 

Over the past several months, ASP researchers have investigated 108 new domains and subdomains belonging to the Pravda network, a previously-established ecosystem of largely identical, automated web pages that previously targeted many countries in Europe as well as Africa and Asia with pro-Russia narratives about the war in Ukraine. ASP’s research, in combination with that of other organizations, brings the total number of associated domains and subdomains to 182. The network’s older targets largely consisted of states belonging to or aligned with the West. 

Notably, this latest expansion includes many countries in Africa, the Asia-Pacific, the Middle East, and North America. It also includes entities other than countries as targets, specifically non-sovereign nations, international organizations, audiences for specific languages, and prominent heads of state. The top objective of the network appears to be duplicating as much pro-Russia content as widely as possible. With one click, a single article could be autotranslated and autoshared with dozens of other sites that appear to target hundreds of millions of people worldwide. 

ASP researchers also believe the network may have been custom-built to flood large language models (LLMs) with pro-Russia content. The network is unfriendly to human users; sites within the network boast no search function, poor formatting, and unreliable scrolling, among other usability issues. This final finding poses foundational implications for the intersection of disinformation and artificial intelligence (AI), which threaten to turbocharge highly automated, global information operations in the future.

A pro-Russia content aggregation network is churning out at least 3 MILLION pieces of propaganda per year, all on sites that are virtually unusable by humans.

So what's the goal? We explore the idea that it might be to flood LLMs with pro-Russia content:

Meta built a global fact-checking operation. Will it survive? The company's policy reversal comes as the U.S. is diverging sharply from other countries over regulating social media.

"I'm just a simple European but…the United States seems to be the only country in the world where adding information is seen as censorship," said Maarten Schenk, Lead Stories chief operating officer and co-founder.

Global Risks Report 2024 | World Economic Forum The Global Risks Report 2024 from the World Economic Forum explores some of the most severe risks we may face over the next decade. Read the report to learn more.

I guess no method can accurately predict or evaluate future risks. Each methodology has its limitations and pitfalls. Aggregating experts' research results and opinions has some value, nonetheless, I suppose. Here's the full report. www.weforum.org/publications...

Revisiting this report/graphic. Wonder how the "risk" has materialised in these countries this year.

It tries to explain two circulation types: 1) organic spread driven by human psychology/natural behaviours; 2) coordinated efforts orchestrated by motivated actors with vested interests. Distinguishing them helps discuss mitigation/intervention strategies for each, as their target outcomes differ.
