Zaps to alert for PHI?

Hi! I manage a community for a healthcare company and one of the things we are concerned about is any post that could contain PHI (personal health information). We have definitely included that warning multiple times in guidelines and on the community, but I was thinking that it might be good if we could create a Zap if any PHI is shared. I’m not sure how this would work or if Gainsight has any triggers on this, but I’d love to hear ideas from folks here.
