Reddit Implements Human Verification to Combat Bot Activity

Reddit's potential rival, Digg, recently shut down after failing to control the bots that overran its platform. On Wednesday, Reddit announced it is tackling this challenge head-on.

The company will start labeling automated accounts that provide a service to users, similar to how "good bots" are identified on X. It will also require accounts suspected of being bots to verify they are human.

Reddit emphasizes this is not a sitewide verification mandate. It will only be triggered if an account's activity or technical signals suggest it is not human. Accounts that fail the verification may face restrictions.

To spot potential bots, Reddit uses specialized tools that analyze account-level signals and behaviors, such as the speed at which an account attempts to post content. Notably, using AI to write posts or comments is not against Reddit's policies, though individual community moderators may set their own rules.

For human verification, Reddit will utilize third-party tools like passkeys from Apple, Google, and YubiKey, as well as biometric services like Face ID or even Sam Altman's World ID. In some countries or U.S. states, government IDs may be required due to local age verification laws, though Reddit states this is not its preferred method.

"If we need to verify an account is human, we'll do it with privacy as our top priority," wrote Reddit co-founder and CEO Steve Huffman in the announcement. "Our goal is to confirm there's a person behind the account, not to identify who that person is. We aim to increase transparency about what is automated on Reddit while preserving the anonymity that makes our platform unique. You shouldn't have to sacrifice one for the other."

These changes address the growing issue of bots across social platforms and the wider web, where they are often used to influence politics, spread misinformation, artificially inflate popularity, conduct covert marketing, generate fake ad clicks, and more. According to Cloudflare, bot traffic—including web crawlers and AI agents—is projected to surpass human traffic by 2027.

Reddit has become a particular target for bots that attempt to manipulate narratives, astroturf for companies, repost links, post spam, drive traffic, or conduct research. Furthermore, because Reddit's content is used to train AI models through lucrative deals, there is suspicion that bots are even posting questions to generate more training data in areas where AI lacks information.

Reddit's other co-founder, Alexis Ohanian, has also commented on the related "dead internet theory"—the idea that bots outnumber humans online and that most content, interactions, and web activity are automated or AI-generated. In the age of AI agents, this theory is increasingly becoming a reality.

The company announced last year it would begin requiring human verification in response to the bot surge and to meet evolving regulatory requirements. However, Reddit notes that current solutions, which Huffman recently discussed on the TBPN podcast, are not ideal.

"The best long-term solutions will be decentralized, individualized, private, and ideally won't require an ID at all," Huffman wrote in today's announcement.

Alongside these updates, Reddit stated it will continue removing bots and spam, averaging 100,000 account removals per day, and will rely on user reports of suspected bots, with improved tools on the way.
