Domain seizure is a legal process where government authorities take control of a website's domain name, often as part of investigations into illegal activities such as copyright infringement, fraud, or cybercrime. When a domain is seized, users attempting to visit the website are typically redirected to a notice explaining the seizure. This action disrupts access to the targeted online service and serves as a warning to others. Domain seizure is commonly used to combat online piracy, illegal marketplaces, and other unlawful digital operations.
