If you’ve posted on LinkedIn recently, you might have encountered comments that are unreasonably quick once you’ve posted, sound strangely formal, follow the same structure, or simply repeat your own post back to you. These are often signs of automated AI commenting tools.

So why do people use them? They think it will drive more visibility of their profiles as comments can attract attention, and lots of engagement tells LinkedIn’s algorithm that a post is worth showing to more people.

Interestingly these tools already violate LinkedIn’s terms of service, but some users have continued to use them as they think they know better.

However, LinkedIn is building systems to detect low-quality AI comments by analysing both the language used and behavioural patterns by (ironically) using AI.

Someone relying on automation, for example, might comment far more frequently and much faster than a typical user.

Apparently, “Great insights! Thanks for sharing your valuable perspective!” copied 47 times before lunch is beginning to raise suspicion – who’d have thought it 😊
