No one person currently regulates the dark web. Each individual
peer-to-peer network is owned and operated independently. Since most
of it is anonymous, the government (U.S. National Security Agency) has
very little way of finding out who owns what. However, they do have
specialized hackers who regularly work on the dark web, and they do
try to shut down the more serious offenders offering child pornography,
guns, and illegal drugs. Sometimes it takes years to locate the
actual perpetrators.
