Meta Allegedly Used Millions of Web Domains for AI Training

Executive Signal Summary

A leaked Drop Site News list allegedly shows Meta collected training data from around six million domains, spanning major brands like Getty Images and Shopify to niche sites and adult content. The leak claims Meta’s internal crawler, 'Spidermate', bypassed robots.txt protections to harvest data, with CDNs enabling repeated access even after pages were removed. The list reportedly includes domains containing sensitive or copyrighted material, and some possibly illegal content. Meta denied the accusations, with spokesperson Andy Stone calling the list 'not real' and posting that the list is bogus. The piece notes prior reporting on Meta planning to standardize EU-user data for AI training with an opt-out option and discusses regulatory uncertainty around data usage, copyright, and AI training transparency, highlighting broader industry debates and potential publisher implications.

Meta tracks employee keystrokes for AI training

Meta has deployed an internal tool, the Model Capability Initiative (MCI), to capture employee on-screen inputs — including keystrokes, mouse clicks and navigation — across hundreds of websites and apps to build data for training its AI models. CNBC reviewed an internal memo and reporting says sites monitored include Google, LinkedIn, Wikipedia, GitHub, Slack, Salesforce, Atlassian and Meta properties such as Threads and Manus. The project is linked to CEO Mark Zuckerberg’s push to accelerate generative AI, including hires and new models like Muse Spark; Meta says safeguards are in place and the data will not be used for other purposes. Internal messages show employees raised privacy and sensitive-data exposure concerns. Reuters previously reported on the tracking tool.

Meta Data Leak: Tracking Tool Exposed Personal Data

Meta faces a security incident after internal tracking software—introduced in April as the "Model Capability Initiative" to capture mouse movements, clicks and keystrokes for AI training—apparently exposed employee data company‑wide. Over 1,600 employees had previously petitioned against the tool on privacy grounds. Reporting based on an internal security notice indicates information from 45,000 tables was accessible, including full prompts and transcriptions, private conversations, and personnel and performance data. Meta told Wired it is investigating, has disabled the data-collection program pending that probe, and a company CTO acknowledged implementation fell short of privacy-review standards. The incident has deepened internal morale issues following recent layoffs and reassignments.

Meta Logs Employee Inputs for AI Training

Meta is rolling out a program called the Model Capability Initiative (MCI) that will run on employee work computers to capture mouse movements, keystrokes and intermittent screenshots across work apps and websites to generate training data for AI models. Reuters reported the initiative based on internal memos; a Meta spokesperson confirmed the tool and said data will not be used for performance evaluation and that security rules are in place to exclude "sensitive content," without detailing exclusions. Some employees described the monitoring as dystopian, and legal experts told Reuters that similar surveillance likely would be unlawful in Europe. Meta says the data will help make AI agents interact more naturally with computer interfaces. The deployment appears focused on the U.S. and comes amid broader Meta AI investments and workforce reductions concerns.
