I understand it's common for scammers to follow this route. With the modern "tech support" telephone scams, they apparently do the same thing, and if the first wave has scammed you out of money, you'll get multiple additional waves that'll either try different scams, or build upon the first one and pretend to be a police investigator etc. It's strange to me that there aren't more coordinated investigations. Individually, these will often be smaller sums, nothing that'll justify international police actions, but collectively the damage is huge. Even just one gang will reach millions of USD. They're not criminal master minds, Youtubers are able to track them down.
