For example, Quantum Communications claimed to Mass Music, an innocent customer that they'd send a mailing to people who'd asked to receive info about new products and services, not to thousands of unwilling spam recipients. Now Mass Music's made thousands of new enemies who will never buy from them after to being spammed, due to Quantum's misrepresentations. Another, similar, lie is to sell someone a mailing list and tell them that the people on it want advertising e-mail. Most of the time, the list is one of the same old spam lists that's been around five years. There are a very few lists of people who've signed up for ads, but they're small, targetted, anot not cheap.
Any large list purporting to be of people who want any kind of advertising e-mail is a fraud.
Spammers also cheat their suppliers. A number of ISPs have admitted that many or most of their spammers never pay for their service. This is especially true with the spammers who use free trial accounts with a provider to send their spew. It's obvious in those cases that they never intended to pay.
