Anthropic blocks hundreds of Russian Claude accounts

Anthropic blocked several hundred profiles of Russian users of the Claude neural network without warning. Those affected include ordinary users as well as professionals — developers, designers and content creators who use the service for work.

How it happened

The wave of bans came without notice and hit hundreds of accounts across Russia at practically the same time. Users found their access closed when they tried to log in, and received no notifications, explanations or advance warnings. This differs sharply from the usual practice for web services, which typically give at least some explanation.

Those affected began discussing the situation actively on social media and in professional communities. Among them were people for whom Claude was the main productivity tool.

Possible reasons

Anthropic is a US company and is automatically subject to US law, including sanctions regimes. The US has imposed numerous restrictions on providing American services to residents of Russia. The mass scale of the blocks suggests this was not a response to individual violations but a systemic decision:

• Possible application of US sanctions mechanisms
• The lack of warning is typical of compliance with government requirements
• Blocking many accounts at once points to an automated decision

However, Anthropic has still not issued an official statement on the reasons.

What this means

The situation shows how geopolitical factors directly affect the availability of Western services. For Russian businesses, this strengthens the trend toward localization: Yandex.GPT, MegaMozg and other local solutions are becoming more dependable in terms of access stability. Claude has lost its position as the unquestioned choice for critical workflows.
