FCC Chairman Ajit Pai has acknowledged that about 500,000 of the comments were tied to Russian email addresses, but the agency under his leadership has so far refused Freedom of Information Act requests for server logs that could help reveal the people responsible for the fake comments. The FCC claimed that the data could expose the US to cyberattacks, but Commissioner Jessica Rosenworcel argued that the regulator is merely trying to "hide" behind FOIA exemptions.

More than half of the nearly 22 million comments were fake, according to one study, and only 17.4 percent were unique. Many of them repeated the same pro-repeal messages almost verbatim, and many of them used fake email addresses from a handful of domains. On top of what looks to be Russian meddling, there are concerns that telecoms or anti-regulation groups may have flooded the comments with fake grassroots support to make it seem as if the public was on their side. Most of the genuine comments opposed the repeal.
