Researchers built an AI that doxes any "anonymous" reddit account in under a minutes for $2. eth zurich and anthropic published a terrifying paper proving that "practical anonymity" on the internet is officially dead. they built a fully autonomous ai pipeline that takes your pseudonymous posts, extracts your identity signals, searches the web, and figures out exactly who you are. no human investigator needed. the numbers are actually mindblowing.. - 67% of hacker news users identified correctly - when the system makes a guess, it is right 90% of the time - it even unmasked scientists whose interview transcripts were explicitly redacted for privacy the scariest part? even time doesn't protect you.. they tested users who took a full year break and changed their interests. the ai still matched their old and new profiles with 90% precision. it sees through your persona changes like they aren't even there. there is no defense against this. the agent splits the work into tiny, benign tasks like "summarizing a profile" or "ranking candidates." no api safety guardrail is going to flag it because no single step looks malicious.. every throwaway account. every "nobody will connect this to me" comment. it’s all just searchable micro-data now.

I don’t know how to increase the impression on this tweet. But this is an extremely urgent call I’m urging everyone to speak up about: Iran is at war. 90 million people have had NO internet for 14 days. They can’t warn each other about attacks. They can’t call their families. They can’t tell the world what’s Internet experts inside Iran are telling me the outside world and @elonmusk can actually help. This is how: The solution exists NOW: ✅ 650+ satellites ready ✅ Works with regular phones ✅ One FCC signature away #DirectToCellForIran #DigitalBlackOutİran

Replying to @googlemaps
@googlemaps changed the name of the longest street in Tehran (and one of the longest in the world) from "Valiasr" to "Pahlavi" street, its original pre-Islamic revolution name

🚨 Holy shit… Stanford just exposed that every major AI company is using your private conversations to train their models by default. They analyzed the privacy policies of OpenAI, Google, Meta, Anthropic, Microsoft, and Amazon. Reviewed 28 separate documents across all 6 companies. The findings are worrisome. Every prompt you type. Every file you upload. Every personal detail you share. All of it feeds directly into model training the moment you hit send. That health question you asked ChatGPT at 2am? Training data. Legal situation you described to Claude? Training data. The photo you uploaded to Gemini? Training data. Some companies retain your conversations INDEFINITELY. Amazon, Meta, and OpenAI have no confirmed deletion timeline for certain chat data. Your most private conversations could sit on their servers forever. It gets worse for kids. Four out of six companies allow children aged 13-18 to use their chatbots, and most don’t treat children’s data any differently. Kids’ conversations are likely getting fed into model training by default. Kids who can’t legally consent to it. Here’s something most people missed: enterprise customers are opted OUT of training by default. You, the consumer paying $20/month? Opted IN. Companies paying thousands? Protected automatically. There’s a two-tiered privacy system and you’re on the wrong side of it. OpenAI even frames the opt-in with guilt. Their settings page says “Improve the model for everyone.” Stanford’s researchers flagged this as a textbook dark pattern designed to make you feel bad for protecting your own data. Meta’s contractors told reporters they routinely see identifiable personal information in the chat data they review. Journalists were able to positively identify at least one real person from chat transcripts shared with them. The privacy policies themselves? Stanford had to dig through 6 separate documents just for OpenAI alone. Most real disclosures were buried in sub-policies no normal person would ever find. The researchers said it was challenging for THEM to piece it together. For consumers? “Practically impossible.” Only Microsoft explicitly stated they try to remove personal data like names, phone numbers, and addresses before training. The rest are either vague about it or completely silent.

UPDATE: Iran Internet shutdown Continuing to see a small, but steady restoration of traffic for Iran as the country rolls out its internet whitelisting system to police connectivity. #DigitalBlackoutIran #IranianRevolution2026 From our perspective, traffic is at ~25% of pre-shutdown levels (bits/sec).

Iranian people are expressing real and long-standing grievances over economic hardship, corruption, political repression, and lack of accountability for government officials. These demands are legitimate and deserve to be heard on their own terms. And they have been met again with force by Iranian authorities. They are also unfolding in a context of intense external pressure of sanctions, regional destabilization, and war that have heightened insecurity across the region. Supporting protests in Iran means holding two truths at once: standing with people inside the country and their demands for dignity and rights, while remaining clear-eyed about outside forces that seek to exploit economic pain and political frustration to advance agendas of destabilization—not liberation. True solidarity rejects both repression at home and intervention from abroad. It centers Iranian agency and refuses to allow internal dissent to be hijacked by external forces.
