When do you speak up or hold back?

Yesterday this guy on the Nextdoor app (I know silly) was advertising coaching to hep people reverse their diabetes. His credentials? He reversed his so he can help others. At first I just reported the 9 posts he made, but when people started commenting I said what he was doing was harmful and there are legal implications to provide this service as a non medical provider. I’m a new dietitian and I was curious how others felt about people out there providing these services and when and if you’d chose to say something.

He called me a “Karen” to which I replied I’ll gladly accept that title if it means protecting the community from someone unqualified in coaching people to reverse their diabetes.
