What is the fastest way you can tell a LinkedIn post was AI-written?

LinkedIn says it’s going after AI slop - https://www.entrepreneur.com/business-news/linkedin-is-fighting-back-against-ai-slop-and-ai-comments. My feed is full of posts that feel like they were written by a very polite HR ghost. Clean intro, three lessons, fake vulnerability. & perfect punctuation. It think it’s not always the use of AI that gives it away but it’s the lack of fingerprints.

No odd phrasing

No specific memory

No real irritation

No sentence that feels like someone typed

We’re building imperfectly.app around this problem.
