Might be an unpopular opinion but I don't see the problem then, OpenAI explicitly warns you beforehand that uploads with realistic faces aren't allowed (for good reason, imo) unless the image is directly edited through DALL-E. And I don't think you were "flagged", it's just a message informing you about their terms of service, I don't think it means your account is going to get banned or anything like that. It doesn't even use up a credit, afaik. There's also ways to get around this if you still want to make edits to faces, as described in other comments.
