A researcher who went under cover in the metaverse as a 13-year-old girl witnessed grooming, graphic sexual material, and threats of rape.

The researcher, the BBC reported, used an app with a minimum age rating of 13 and visited virtual reality rooms where other users’ avatars were simulating explicit acts. The researcher, whose online presence depicted that of a 13-year-old girl, was shown sex toys and condoms and approached by several adult men.

One man told the researcher that in the metaverse, users’ avatars can “get naked and do unspeakable things.” Other users approached the researcher while in the metaverse and discussed “erotic role-play.”
