"Here, disclosing the originating IP addresses and user-agent headers would help clarify whether and to what extent fraudulent activity interfered with the comment process for the FCC's [net neutrality repeal], and more generally, the extent to which administrative rulemaking may be vulnerable to corruption. This serves a vital public interest because of the importance of public comments in agency rulemaking," Schofield wrote.
