# AdultBlock

A blocking service from the registry that launched .xxx, now part of GoDaddy Registry. It keeps a trademark from being registered in the four adult-themed TLDs: .xxx, .adult, .porn and .sex. It is open to marks recorded in the Trademark Clearinghouse. A higher tier, AdultBlock+, also blocks look-alike spellings.
