Social media platforms; adverse action; user's page or account; notice; hearing; temporary restriction; right of action; effective date.

HB 3523 requires large social media platforms (with over 100 million global users accessible in Oklahoma) to provide users with detailed written notice before taking adverse actions like suspensions or deletions. This notice must specify the violated rule, content in question, evidence, and proposed action, followed by a 7-day response period and human review. Platforms may temporarily restrict accounts to prevent imminent harm only if they provide 24-hour notice and hold a full hearing within 7 days, restoring accounts if the action isn't justified. Affected users gain a right to sue for $10,000 per violation or seek injunctive relief, while Oklahoma's Attorney General can enforce the law with civil penalties up to $25,000 per violation. The law takes effect November 1, 2026.
