We would like to emphasize that we are not the webhost of the website you are referring to, so we are not responsible for the web-content, we also do not offer any kind of email-services.
Hexonet provides only domain-registration services. We therefore suggest that you contact the responsible webhosting provider at first as they may eliminate any infringing content from the root in the first place.
As an ICANN Domain-Registrar, we are only permitted to suspend / delete a domain if we receive a binding document from an authorized dispute resolution body such as WIPO, court orders from a competent jurisdiction, or instruction by the respective Registry or by a request of the police.
You may also start a legal proceeding against the domain owner or webhost in the competent jurisdiction.
In addition, you may file a complaint at your local police station.
