I can attest that the FBI has in fact been tracking these guys for more than a decade, and some of them were indicted previously. What I can't understand is why it took so long for this latest, more broad action, and why there is such a huge time gap between the victims referenced in the indictments. There are victims listed from 2010 and 2011 and then some this year (2019), but hardly any in between.

That said, the FBI is not in the pre-crime business (with few exceptions), so they're not really set up to warn businesses like I did for so many years.
