X Cracks Down on AI Reply Spam, Forcing InfoFi Platforms to Rethink Pay-to-Post Models

X has moved to rein in a growing wave of AI-generated reply spam by shutting the door on a controversial corner of crypto-powered social media. A recent update to the platform’s developer API now bans apps from rewarding users with tokens, points, or cash for posting or engaging, effectively dismantling the core model behind many so-called InfoFi projects.

The decision has been widely welcomed by everyday users, analysts, and prominent tech figures who say automated replies and engagement farming had begun to overwhelm timelines. At the same time, it has triggered sharp fallout across the crypto ecosystem, where several platforms built around paid posting are now scrambling to adapt or shutting down entirely.

A clear line on paid engagement

Under the revised rules, any API-connected application that distributes financial rewards in exchange for engagement is no longer permitted. X has already revoked access for multiple projects and signaled that enforcement is active.

While the company stressed it remains open to crypto and web3 developers, the update draws a firm boundary around one specific idea: paying people to post.

“There are incredible use cases for CT and crypto/web3 with X API which we will continue to support and showcase,” X developer Chris Park wrote in a post on Thursday, adding that new launches and updates are on the way.

The message was clear. Experimentation is welcome, but incentive structures that fuel spam are not.

How InfoFi turned attention into currency

InfoFi, short for information finance, refers to platforms that attempt to turn social media activity into a market. Users are rewarded for posting, amplifying, or reacting to content that algorithms identify as relevant or trending.

Supporters argue that these systems surface useful information more efficiently. Critics counter that they do the opposite, encouraging low-effort replies, repetitive comments, and bot-driven noise.

Kaito became one of the most visible examples of the model. Its AI system aggregates posts from influential crypto accounts to spot emerging topics, then rewards users who help push those conversations further. Following X’s API changes, Kaito’s KAITO token dropped sharply, reflecting concerns that its core mechanics may no longer be viable.

Growing frustration with reply spam

The crackdown comes after weeks of public criticism from figures inside and outside crypto. X product chief Nikita Bier, an advisor to Solana Labs, argued in a now-deleted post that crypto Twitter was harming itself by wasting limited user attention on empty engagement.

Most users, he noted, see only a few dozen posts a day. Filling that space with “gm” greetings and automated replies crowds out more meaningful content.

That dynamic mirrors the broader attention economy, where likes, impressions, and clicks are easily monetized. Once financial incentives are attached, volume often wins over quality.

“You create a financial incentive for someone to post, it creates more of it,” said Nic Carter of Castle Island Ventures. “Combine this with AI and you get tons of slop.”

Others were even more blunt. Taproot Wizards founder Udi Wertheimer questioned why anyone would use direct access to influential audiences to “farm points” instead of sharing original ideas.

The backlash extended beyond crypto circles. Bloomberg Intelligence analyst James Seyffart praised the move, saying limits on reply spam are badly needed. Y Combinator founder Paul Graham echoed the sentiment, describing AI-generated replies as a “plague.”

Immediate fallout across InfoFi platforms

The policy change had swift consequences. COOKIE, another InfoFi project, saw its token fall into double-digit losses and announced plans to sunset its current platform. Kaito said it will abandon its token-driven approach and pivot toward a more traditional influencer marketing model.

Founder Yu Hu said a fully permissionless reward system no longer aligns with the needs of brands, creators, or X itself. Going forward, Kaito Studio will focus on curated partnerships with creators who meet defined criteria and deliver against clear briefs.

Other platforms are pausing to reassess. Xeet, which runs gamified brand campaigns, halted all activity while it evaluates next steps and works through outstanding payouts. Some projects, such as Noise, say they are unaffected, arguing that their use of social data does not rely on incentivized posting.

Debate over motives and monetization

Not everyone sees X’s move as purely about improving discourse. Some critics argue the platform is drawing boundaries to protect its own monetization strategy. In late 2024, X shifted creator payouts to be based on engagement from premium users rather than ad views.

“If financial incentives to post create spam, that logic applies everywhere,” said Chainlink community liaison Zach Rynes, suggesting the issue may be more about control than content quality.

Others believe the problem runs deeper. As long as engagement itself is rewarded, some level of gaming is inevitable. Even if InfoFi fades, the incentives that drive low-quality posting remain.

A reset for social crypto experiments

For now, X’s API changes mark a decisive reset. Paying users to post may have been one of crypto’s most ambitious social experiments, but it also proved how quickly incentives and automation can degrade online conversation.

As platforms adjust and new models emerge, the broader question remains unresolved: how to reward valuable contributions without turning timelines into noise. What is clear is that, at least on X, the era of token-powered reply farming is coming to an end.
