EU opens formal probe into Shein over childlike dolls and platform design

The European Commission has launched a formal investigation into Shein to assess potential Digital Services Act breaches, including the sale of childlike sex dolls, the platform’s addictive design, and the transparency of its recommender systems. The EC notes possible enforcement steps and penalties up to 6% of global sales, while Shein says it is strengthening compliance and protections for younger users and has cooperated with authorities amid prior France-related inquiries.

Facebook Reels Refines Recommendations Using User Survey Feedback

Facebook Reels enhances personalization by deploying the User True Interest Survey (UTIS), a survey-driven alignment layer atop the main ranking model. Daily in-context surveys measure how well videos match user interests, boosting niche content and engagement. Offline metrics improve from 59.5% to 71.5% in accuracy, 48.3% to 63.2% in precision, and 45.4% to 66.1% in recall; online A/B tests show higher engagement and fewer integrity issues. UTIS is integrated in late-stage ranking and early-stage retrieval via a Perception Layer to handle sparse feedback, with future work focusing on bias reduction and more advanced modeling.
