Pangram: Over 40% of LinkedIn Long Posts AI-Generated
Pangram Labs, maker of an AI-text detector, analysed social-media posts users actually encountered across platforms and found a high prevalence of AI-generated text. The study reports that more than 40% of LinkedIn posts longer than 250 words were classified as fully AI-generated. Pangram claims a 99.98% detection accuracy, supported by independent studies at the University of Maryland and the University of Chicago. Across the sampled platforms the average AI share was 13.8%, with longer posts more likely to be AI-generated; on X Pangram classified 25% of content as fully AI-generated and 23% as AI-assisted. LinkedIn has publicly commented on the rise of so-called "AI Slop" and said it will respond to the trend.
LinkedIn Second Most-Cited AI Answer Source
Meltwater analyzed 9.5 million AI citations across 16 B2B categories using its GenAI Lens and found LinkedIn is the #2 most-cited source by AI models, behind YouTube. The research shows individual LinkedIn member profiles generate roughly 75% of LinkedIn citations versus 25% from Company Pages, and that structured, expert-driven content (headings, lists, named entities, quantitative data) is more likely to be cited. More than half (51%) of LinkedIn citations came from members with fewer than 10,000 followers, indicating AI favors relevance and clarity over raw reach. Meltwater also found platforms like LinkedIn, Reddit and YouTube account for 47.5% of AI citations, compared with 15% from peer-review sites and 18.7% from company websites. Meltwater and LinkedIn executives quoted in the release framed these findings as evidence that AI discoverability now determines brand consideration in B2B buying.
LinkedIn adds 'Seems like AI Slop' report button
LinkedIn has rolled out a global “Seems like AI Slop” reporting feature that lets members flag posts they suspect were generated by AI, a change announced by senior product manager Hari Srinivasan. Community reports will feed classifiers to help identify and downrank interchangeable AI-written content, while suspected inauthentic posts will also be privately flagged in creators’ dashboards to solicit human feedback. LinkedIn says it has blocked billions of automated publishing attempts and hundreds of thousands of automated comment attempts daily. The company removed its generative “Enhance your post” tool in favor of a lighter proofreading assistant, added verification and comment-blocking controls, and is testing improved models to promote content with clear personal perspective. Rollout is gradual and availability in Germany has not been specified.
