What you are telling us sounds important to me.
You say that it is important for victims to report fraud to the authorities so that the authorities can better understand the schemes. You also mentioned the influence of the media in all this.
It's certain that my reflexes are those of a French speaker. If I receive a call in English, I suspect it may be a fraud. I can hang up immediately.
Have you seen any cases of fraudulent calls in French? Honestly, I have the impression that it happens much more in English than in French. What about the French side?
