Sure, that's if human moderators see it before the AI, in which case, why have an AI at all? I presume in this solution that the AI is running all the time and it will see messages the instant they're sent and thus will always be vulnerable to a prompt injection attack before any human even sees it in the first place.
That's what you tell the AI to do, who knows what other systems it has access to? For example, where is it writing the flags for these posts? Can it access the file system and do something programmatically? Et cetera, et cetera.
OpenAI doesn't allow write access to any file system. If you are recording posts to be reviewed, then you must necessarily store that information somewhere, at which point you will be allowing the AI to access some sort of data storage system, whether it be a file system or a database.
