Detroit Timber & Lumber Co., 200 U. S. 321, 337. SUPREME COURT OF THE UNITED STATES Syllabus LINDKE v. FREED CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR THE SIXTH CIRCUIT No. 22–611. Argued October 31, 2023—Decided March 15, 2024 James Freed, like countless other Americans, created a private Facebook profile sometime before 2008. He eventually converted his profile to a public “page,” meaning that anyone could see and comment on his posts. In 2014, Freed updated his Facebook page to reflect that he was appointed city manager of Port Huron, Michigan, describing himself as “Daddy to Lucy, Husband to Jessie and City Manager, Chief Administrative Officer for the citizens of Port Huron, MI.” Freed continued to operate his Facebook page himself and continued to post prolifically (and primarily) about his personal life.

Freed often responded to comments on his posts, including those left by city residents with inquiries about community matters. He occasionally deleted comments that he considered “derogatory” or “stupid.” After the COVID–19 pandemic began, Freed posted about it.

The District Court determined that because Freed managed his Facebook page in his private capacity, and because only state action can give rise to liability under §1983, Lindke’s claim failed. The Sixth Circuit affirmed. Held: A public official who prevents someone from commenting on the official’s social-media page engages in state action under §1983 only if
