What is the Adult Block Service?

Are you interested in protecting your brand name from misuse? The AdultBlock Service is a new rights protection service specifically for brand holders. It has been designed to enable brand holders to reserve names aligned with their trademark or brands for protection of their naming rights across adult themed TLDs. This service will allow trademark holders to affordably block exact match terms and the many thousands of look-alike variations that can be easily generated by bad actors to spoof users to visit websites containing malicious code used in phishing and malware scams.

The four adult themed TLDs included are: .adult, .porn, .sex and .xxx.

There are 2 categories for this protection service:

  • The AdultBlock service ensures the registered term will be blocked in all four TLDs and automatically block any dropped names irrespective of the price of the domain name (e.g. Premium Domain Names).
  • The AdultBlock+ service goes even further with all the protections of the AdultBlock coupled with the ability to block plurals, all look-alike variations that appear confusingly similar to the trademarked term (e.g. β, braп, branꓒ.com,,, exα,,, eх, etc).


AdultBlock was originally open only to companies with a record in the Trademark Clearing House or who participated in the .xxx Sunrise B program. But, following the success of this service, AdultBlock and AdultBlock+ can now be requested by holders of registered trademarks that are not in the Trademark Clearning House, owners of unregistered trademarks such as business names and celebrities.
