One of the most alarming notices users have encountered is the alert regarding
malicious attacks on DeepSeek's platform. Due to these attacks, the service has temporarily limited new registrations, specifically requiring users from mainland China to register with a Chinese phone number (source:
The Verge). The alert, which reads, “
Due to large-scale malicious attacks, registration may be busy. Please wait & try again,” can leave potential users frustrated with the situation.
