I believe those are the primary income of ID thieves.
==========================================
Perhaps some people get money this way, but most ID thieves seem to seek out the ID's of cardholders who pay their bills, because most people with bad credit do not get such things in the mail. I get those credit card cash advance checks, too, but I have never used one. I shred them before I throw them away.
I did get billed for buying two tanks of Diesel instead of one on the same day, but I reported it, it was taken off my bill and I have never used that Sunoco station again.
At the moment banks are sitting on a huge amount of money and not lending it out to businesses and people trying to buy houses. Credit cards seem to be the only way that they lend money, but these are small amounts.
