Top Level Domain (TLD) registries which allow registrars to sell high volumes of domains to professional spammers and malware operators in essence aid and abet the plague of abuse on the Internet. Some registrars and resellers knowingly sell high volumes of domains to these actors for profit, and many registries do not do enough to stop or limit this endless supply of domains.
