I worked with the fraud team implementing the security for a real time data ingestion pipeline at a major bank partner. I am a bit more informed on this than the average hn poster :)

It's literally less information versus directly letting them know. One message lets them know you know, and the other doesn't.

> Forcing the fraudster to call if they want more information - excellent.

But there's something else you're not taking into account, which is innocent people who trigger your fraud detection.

>Cussing - doesn’t make a difference either way from an information perspective.

Well it certainly lets the fraudster know you know. A legitimate customer receiving that kind of abuse would be pretty unusual, don't you think?

You’ve mistaken me for the average. I’ve worked in Integrity for a FAANG company and in FinCrime for a bank. I have a very good idea of how to mask information from bad people automating things. That’s literally all I’ve done for more than half a decade.

Save your condescension for someone else.

It doesn't change that this is basic logic. One yields less information than the other, and you didn't grasp that. Sorry if I came off as condescending. I don't really see a point in continuing this conversation.
