LinkedIn is the undisputed king of long-form AI slop, according to a study spanning five platforms

A study by Pangram Labs found that 41 percent of long-form posts on LinkedIn are entirely generated by artificial intelligence. While the platform accounted for only one-third of the total posts analyzed, it contained nearly two-thirds of all detected AI-written content across five major social networks. This concentration suggests that LinkedIn has become a primary hub for automated, high-volume content compared to other platforms.
