When they targeted B&B owners, they might have bitten off more than they can chew on.
Here is a warning from "Pillows and Pancakes" - a magazine covering the B&B industry:
The end goal is to get the B&B owner to send money to the scammer. Typically, the scammer will make a booking and overpay for it with either a credit card or forged check. The scammer will request the balance sent somewhere, usually by Western Union. Remember, these scammers are creative and there are many variations on the scam.To read more on the different variations, link here.

On a closing note, I would like to welcome the B&B folks to this effort to rid the Internet of these "less than desirable" users!
