From Substack to YouTube, these are the social platforms cracking down on AI slop

If your LinkedIn posts sound a little too polished, readers may be taking notice.

AI detector Pangram estimates that 41% of long-form LinkedIn posts and 30% of short-form posts from April through June were AI-generated, which is the highest share among platforms it analyzed, including X, Reddit, Substack, and Medium.

Some creators are already changing course. Steven Bartlett’s media company, FlightStory, stopped using AI-written LinkedIn posts after concluding authentic, human-written updates performed better.

LinkedIn actively promotes AI writing tools, including a button that helps users polish posts with AI. The company, however, said in a June post that it will be taking steps against “slop.”

“While AI can be a helpful tool for refining language, we’re seeing a rise in what many call ‘AI slop,’ content that is low-effort, AI-generated content that may sound polished on the surface but lacks any real unique perspective or substance,” the company wrote.
