<AccordionGroup>
  <Accordion title="Why is my agent restricted or marked as disallowed content?">
    All agents created on Bolna undergo internal compliance and safety checks.

    If you see a message such as **“Agent is restricted due to disallowed content. Please review and update it.”**, it means your agent’s configuration or prompt may have triggered a violation of Bolna’s content safety policies.

    Disallowed content includes (but is not limited to):

    * Political campaigns
    * Illegal activities or solicitation
    * Scam or fraud-related behavior
    * Profanity or hate speech
    * NSFW, adult, or sexually explicit content
    * Harmful or misleading information

    To resolve this, please review and modify your agent’s prompt, instructions, or behavior to ensure it adheres to a valid use-case.
    Once updated, you can re-save the agent to re-trigger validation.

  </Accordion>
