LinkedIn Tops AI Spam Rates on Social Platforms

Artificial intelligence-generated spam represents a major challenge for social media networks. Increasingly advanced AI models can now copy human-style interactions and create convincing images and video clips, which has blurred the lines of online discussion.

But which platforms face the heaviest effects from AI spam? According to a recent report, LinkedIn stands out, with 41 percent of all long-form posts in the app showing signs that they originated from AI tools.

The information comes from Pangram, a technology company that built a browser extension for spotting AI-generated writing online. No AI detection software reaches 100 percent accuracy, so measuring the full extent of the problem remains difficult. Still, based on Pangram’s tracking of average measurements across social media platforms, LinkedIn contains the highest volume of AI-generated content, followed by X, where roughly one-third of long-form posts appear to have been written by AI.

Every platform is handling AI spam. Pinterest has moved to tackle worries about the wave of AI-generated posts that some users claim have completely filled their feeds. It is the only platform so far to add a kind of AI off switch, giving users the choice to cut down on the amount of AI-generated content they see.

Meanwhile, Reddit recently offered details about its work to fight a jump in AI-generated comments and activity. X has also admitted its struggles with AI-generated content.

In March, Nikita Bier, X’s head of product, announced a shift in the platform’s creator monetization incentives. The change targeted a sharp increase in AI-generated deepfakes tied to the war in Iran.

Bier and X owner Elon Musk have both spoken about the expanding effect of AI bots on social apps overall. Musk said in a March 2023 post on X that the development of AI has made it impossible to keep bot armies out of social apps, because it is “trivial to spin up 100k human-like bots for less than a penny per account.”

Musk’s solution involved charging every user for access, on the idea that even a small fee would limit the large-scale creation of bot accounts. But not enough people showed interest in paying for X. In fact, paid social options in general have never connected well with audiences.

On LinkedIn, AI countermeasures have included reach penalties when AI spam is spotted.

Nonetheless, most social platforms remain deeply committed to AI projects. As a result, they actually prefer that users bring AI tools into their online activity instead of turning them off.

Meta, for example, has invested hundreds of billions of dollars into AI development as part of its push to become the global leader in AI technology. But Meta users have not shown strong excitement about the AI tools Meta continues to promote.

These days, Facebook and Instagram users regularly receive prompts to use Meta AI for asking questions, creating images of themselves, and writing posts. Yet when Instagram Chief Adam Mosseri recently announced that IG was adding the company’s latest Muse Image generation tools into the app, replies to his post were almost universally negative.
