A campaign group has complained to the US Federal Communications Commission over its refusal to erase fake comments from a consultation on net neutrality.
Fight for the Future's complaint is signed by 14 people who say their details were used without permission to file anti-net neutrality views.
The campaign group says that some of the comments were posted using the names and details of dead people.
The FCC has voted two-to-one to reverse net neutrality laws enacted in 2015.
The vote was the first stage in the process of repealing the legislation designed to force internet service providers to treat all data traffic as equal.
Americans now have until the middle of August to comment on the proposals.
