People are encouraged to voluntarily self-identify as protesters or dissidents by RSVPing to 'No Kings' events via the mobile app called Mobilize.

“The "No Kings" protest movement is a real series of demonstrations that occurred in 2025 and 2026 against the second Trump administration. Mobilize is a legitimate and widely used event management and volunteer recruitment platform for progressive causes, campaigns, and activist groups, including protest organizers. The platform's stated purpose is to help mission-driven organizations manage events and recruit volunteers. By design, when a person RSVPs for any event on the platform, including a protest, they provide personal data and identify themselves with that specific cause or event. Context: The claim presents this as a potentially nefarious activity. However, Mobilize is a standard organizing tool used by thousands of progressive and Democratic organizations to coordinate events and volunteers. Using such a platform to RSVP for a protest is a common and public way of showing support and intent to attend.”
