LinkedIn and X Are Flooded With AI Spam, Browsing Data Suggests

404 Media · 3 months ago · 35

Pangram's AI detection Chrome extension analyzed roughly a million posts across LinkedIn, X, Reddit, Substack, and Medium and found that 41 percent of longform content on LinkedIn and roughly a third of longer posts on X are likely AI-generated. The study measured AI content users actually encounter during normal browsing rather than estimating the percentage of AI content on the internet broadly, providing evidence that AI-generated posts are prominent on major social platforms. Platform responses vary, with LinkedIn removing AI writing tools from its post button and Reddit launching anti-bot initiatives, while questions remain about what platforms should do to address AI content prevalence.
