Selected Projects and Investigations

See our work at AI Forensics for more recent projects.

Investigating TikTok’s policy response to the Ukraine war in Russia
We monitored the evolution of TikTok’s policy in Russia as the war in Ukraine unfolded. We uncovered that TikTok blocked access to international content for its Russian users without declaring it. In a follow-up investigation, we exposed how loopholes in TikTok’s upload ban policy led the platform to be flooded by pro-Kremlin propaganda. Our report lead 6 US Senators to summon TikTok’s CEO for explanations.

YouChoose.ai: Alternative recommender systems for YouTube
YouChoose.ai is plug-in enabling users and content creators to choose and control their recommendations on YouTube.com. The current release (beta) allows content creators to choose the recommendations on their own content. The long term goal for YouChoose is to be a platform for recommender systems, empowering users to pick an accountable algorithm, aligned with their own interests.

An analysis of YouTube’s promotion of conspiratorial content
Lead author of an audit of YouTube’s recommendation engine. The study was published with the New York Times, and was cited by US Congress in a formal letter to the CEO’s of Google and YouTube. Interviews featured in le Monde and the BBC.
The analysis relied on a monitoring infrastructure paired with a machine learning classifier to detect conspiratorial content.
