ByteDance allegedly engaged in unauthorized scraping of user content from platforms like Instagram and Snapchat in 2017 to populate its app Flipagram and train its 'For You' recommendation algorithm. Former employees reported that this data was used to improve the algorithm's performance for US users. The practice resulted in user impersonation and privacy concerns, with ByteDance allegedly instructing staff to delete accounts only after receiving complaints from affected creators.
ByteDance allegedly scraped short-form videos, usernames, profile pictures, and descriptions of accounts on Instagram, Snapchat, and other sources, and uploaded them without consent on Flipagram, TikTok’s predecessor, in order to improve its “For You” algorithm's performance on American users.

The incident was caused by intentional decisions by ByteDance management and engineers to scrape competitor data as a growth hack for their active app.
Added categories peak at 2: Minor (Psychological Harm, Direct)
In 2017, ByteDance allegedly scraped data from hundreds of thousands of US social media users to train its recommendation algorithm and populate its app Flipagram. While primarily a corporate privacy and terms of service violation, the incident highlights strategic concerns regarding foreign entities harvesting domestic user data to train influential personalization algorithms.
The report focuses on the data scraping and training process of the 'For You' algorithm rather than describing its active runtime behavior or operational mode during the incident.
Minimal or No Risk: The 'For You' algorithm is a personalization and recommendation system used in social media entertainment, which poses low or negligible risk under the EU AI Act.
The 'For You' algorithm's primary function is to personalize and recommend content to users based on their preferences.
The reports are highly detailed and draw on multiple independent former employee sources and internal documents. ByteDance's official response is also included, providing a balanced view.
The incident could be interpreted primarily as a corporate data theft and growth hack campaign rather than an AI safety failure, though the training of the recommendation algorithm connects it to AI.
