If you are temple guard these will happen often enough. Yes, to be useful it needs extension, but the spell can affect multiple people so each time a different person would cast it.
Not obviously, I am just reading it as written. They did not specify threat of physical violence, it say harm. If you steal from me, that harms me, if you wish to malign me, that harms me as well, even if you want to tell the truth about my misdeeds, that will also bring me harm.
