## Summary

Anthropic updated its usage policy on October 8, effective November 12, to prohibit using its Claude models to create or seed fake sources for AI systems and search engines. The rule targets networks of sites posing as independent outlets to manipulate search rankings or AI-generated answers, such as a France-based ad agency’s operation identified in September. That operation involved generating around 8,913 articles across 20 languages using Claude, with each article containing internal links to boost site authority. Anthropic removed the Claude account and banned the organization involved.

The policy consolidates previously scattered rules on deceptive activity, including fake personas, outlets, and reviews, into a new section called *Do Not Engage in Deceptive Campaigns or Artificial Activity*. It also clarifies high-risk use cases, removing automated publishing from the list but retaining requirements for legal, medical, and financial AI outputs. Anthropic enforces these rules against all users, from developers to app builders, and may suspend or terminate access for violations. The company updates its policy annually, citing evolving risks as Claude’s capabilities grow.

## Key points

- Anthropic’s new policy bans seeding fake sources to manipulate AI answers or search rankings, effective November 12
- France-based ad agency used Claude to generate 8,913 articles across 20 languages for fake news sites
- High-risk publishing rules removed; legal/medical AI outputs still require professional review and disclosure

## Why it matters

The policy directly targets a growing tactic to manipulate AI-generated content and search rankings, aligning with Google’s spam policies. It could shift how marketers and agencies use AI for content distribution, especially in high-risk sectors like media and advertising.
