it would be very helpful to have an automatic, impersonal way to address the problem
I think "impersonal" would be worse. They'd be screaming to you offlist about it - "what happened?" "why am I being blocked?" etc. In the past I've trtied to avoid the hard conversations by setting up a notice. It has only exacerated the situation. I don't think you can avoid the hard conversation. You just need to have it, and better initiated by you than by the system.
