Marketing professor Samsun Knight published research titled 'Engagement-based curation and the evolution of taste' in the Journal of Cultural Economics in 2026. ^[1] Instagram said in the same blog post that users who operate AI-generated avatar profiles must update their labels 'appropriately' or the platform will apply limits to the reach of those unlabelled profiles. ^[2] Instagram, a Meta-owned social media platform, announced in a blog post on 2026-09-01 that it will rename its 'AI creator' label to 'AI-generated profile' to increase transparency about AI-generated avatars. ^[3] Spotify stated it will not include AI Personas in any editorial or algorithmic recommendations. ^[4] Spotify, the music streaming company, announced it will begin labeling 'AI Personas' from mid-September 2026. ^[5] Knight argues that engagement-based recommendation algorithms identify content users engaged with most recently and suggest more of the same, while dropping content with limited engagement. ^[6] Knight explains that consumer engagement grows with moderate exposure but peaks and then declines as exposure continues, a phenomenon algorithms often miss. ^[7] Knight warns that algorithms treating current tastes as fixed facts rather than created outcomes confirm past choices and breed staleness and churn. ^[8]
