Cloudflare blocked Perplexity for 6 million hidden requests per day
Cloudflare dealt a crushing blow to Perplexity AI, blocking the search startup’s access to thousands of sites. The reason? Unprecedented scale hidden scanning of web resources despite explicit prohibitions from owners!
According to Cloudflare’s research, Perplexity employed sophisticated methods to mask their bots as ordinary Chrome user browsers on macOS. But the digital camouflage strategy didn’t end there. Perplexity company systematically changed IP addresses, using various autonomous systems to bypass protective mechanisms like robots.txt restrictions and masked activity.
Cloudflare documented 3 to 6 million masked requests from Perplexity daily. Which affected tens of thousands of different domains.
Perplexity’s reaction only adds drama to the situation. Startup representative Jesse Dwyer categorically rejected all accusations, calling Cloudflare’s publication nothing more than a “PR stunt”. And then claimed that the bot mentioned in the report doesn’t belong to the company at all!
Cloudflare excluded Perplexity’s bots from their list of trusted crawlers and implemented additional mechanisms for blocking them.

GPT-5 was hacked in 24 hours2 independent research companies NeuralTrust and SPLX discovered critical vulnerabilities in the security system of the new model just 24 hours after GPT-5's release. For comparison, Grok-4 was hacked in 2 days, making the GPT-5 case even more alarming.
Threats and $1 trillion don't improve neural network performanceYou've surely seen these "secret tricks" for controlling neural networks. Like threats, reward promises, emotional manipulations. But do they actually work? Researchers from the University of Pennsylvania and Wharton School conducted a large-scale experiment with 5 advanced models: Gemini 1.5 Flash, Gemini 2.0 Flash, GPT-4o, GPT-4o-mini and GPT o4-mini.
