The service is primarily intended for holders of .CZ domains who are also public administration bodies, educational institutions, or non-profit companies or organizations.
Upon receiving information that a fake e-shop is hosted on a domain within the .cz ccTLD, we do not remove or cancel the domain from the zone. However, we will check the domain holder's details, and based on the findings, the domain may be included in the verification process, which could lead to the cancellation of the registration (but not due to the content of the domain, rather due to incorrect registration details).
If we receive a decision from one of the relevant authorities (most often the Czech Police), and this pertains not only to risky e-shops, the domain may be blocked from transfer or removed from the zone (or both, depending on the decision's wording).
We monitor the list of risky e-shops on the Czech Trade Inspection Authority's website, as well as similar lists issued by the State Agricultural and Food Inspection Authority and the State Institute for Drug Control , and we include the contacts in the data verification process.
