I think the scary thing is that there is just a ton of names, and I'm sure that they can start sniffing around some of those names to find current issues.
It's like they started sniffing around a money laundering scheme, got a hold of the books, and now there's no telling what they can find because there's so many names and you want to know why they were in the book to begin with.
