Nigerians Fraudsters (More)

I wrote a couple of months ago about Nigerian fraudsters using a relay service intended to aid deaf people in making phone calls to rip off bookstores. It's more widespread than that as this article in City Paper makes clear. The telcos who contract to run this service are paid based on the minutes and don't advise operators to disconnect obviously fraudulent calls.The fraudsters use one of two techniques: either they send a fake money order for a too-large amount and have the extra cash sent elsewhere (thus bilking the person out of the cash, if not also the goods); or they use stolen credit card numbers.
