Users report widespread account terminations for Claude, the AI service developed by Anthropic. Complaints indicate that the company has intensified monitoring of VPN usage, leading to sudden account closures without prior notice.

One user from Hong Kong reported losing access after six months of utilizing NordVPN. Anthropic cited suspicious signals as the reason for the account cancellation. The service is not officially supported in Hong Kong, Macau, or mainland China.

The current wave of restrictions suggests a stricter enforcement of existing regional policies. Among those affected in Russia is Roman Maresov, head of e-commerce at Yandex. Anthropic has not released an official statement regarding changes to its VPN policy.
