The controversy over the portrait rights of the granny sex doll (https://www.sexdollpartner.com/collections/milf-sex-doll) promotes legislative innovation. In the first lawsuit, the children of an old woman sued the manufacturer for unauthorized copying of the mother's torso sex doll (https://www.sexdollpartner.com/collections/torso-sex-doll), which eventually led to the revision of the "Digital Remains Rights Act". South Korea has introduced a special clause: the production of granny sex dolls must pay 5% of sales to the elderly welfare fund. These legal practices provide an important model for the protection of digital human rights in the metaverse era.
