POST /2/users/{id}/following calls with self-serve credentials are rejected; X does not document the status code.\n\nRemove or feature-flag follow actions for self-serve apps and show users a clear message (for example a link to the profile so they can follow in the X app), or move to an Enterprise agreement.",
