Astroturfing

The word plays on AstroTurf, the brand of artificial grass: fake grassroots. It is commonly attributed to U.S. Senator Lloyd Bentsen, who used it in the 1980s to describe a flood of form letters that appeared to come from ordinary citizens. Today it covers any campaign that hides its sponsor to make an effort look organic.

An astroturf campaign has three parts: a sponsor with an interest, a set of personas or intermediaries that present as independent, and a channel that makes the messaging look widespread. The personas can be paid commenters, sockpuppet accounts run by one operator, front groups with neutral-sounding names, or genuine people who were recruited and scripted without disclosure.

The channels are ordinary ones: product and app-store reviews, comment sections, letters to officials, public-consultation submissions, social posts, and petitions. The tell is rarely one post. It is the pattern across many, including reused phrasing, accounts created in the same window, profiles with thin histories, posting rhythms that match a shift schedule, and shared infrastructure behind supposedly unrelated voices.

Analysts investigate by clustering accounts on those shared traits and then tracing the cluster back to a sponsor through disclosures, domain registrations, funding records or admissions. Attribution to a specific sponsor is the hardest step, and responsible analysis separates "this activity is coordinated" from "this party ran it".

Common forms include a batch of near-identical five-star reviews for a product posted within a few days, dozens of "concerned resident" comments on a planning application that share paragraphs, and a network of accounts that all amplify the same talking point about a company's competitor.

Regulators treat some of this as deception. In the United States the Federal Trade Commission has rules and guidance on fake and undisclosed reviews and endorsements, and platforms remove networks of fake accounts under their own policies.

A comms team can be on either side of the problem. It may be the target, with fabricated support for an opposing cause appearing to swamp a public conversation, or it may inherit risk from an agency or vendor that ran an undisclosed campaign on its behalf. In both cases the reputational damage comes from the disclosure, not from the original message.

Knowing that a conversation is manufactured changes the response. Engaging with fake voices as though they were a real constituency wastes effort and can lend them credibility. Documenting the coordination and reporting it to the platform is often more useful.

Astroturfing is not simply paid advocacy. Disclosed sponsored content and openly funded campaigns are legitimate. The defining element is concealment of who is behind the effort.

It also differs from brigading, which mobilizes real participants against a target, and from coordinated inauthentic behavior, which is a platform-policy term that covers astroturf networks among other things. Astroturfing is a strategy; the other two describe mechanics.
