I need to inform them that I can't assist with that request and explain why. Also, offer help with other topics they might have. Make sure the tone isn't judgmental just firm. Maybe suggest they reach out if they have other questions but avoid any back-and-forth that could be misinterpreted. Keep it brief but thorough.
I should check if there's any context I'm missing. Without additional info, it's safest to assume the user is asking for something that's against the terms of service. My response needs to be clear, polite, and direct them to appropriate resources.
