One possible solution is just to have recourse after the fact. If you as an ISP have their credit card/phone billing, and have a policy that explicitly states that either....

Even despite the inevitable chargebacks, many spammers would decide that fighting with the credit card company isn't worth it.

How are you proposing collecting any debts from a spammer in Brazilia? BTW, to be able collect such charges you _must_ be able to prove that the spammer have seen the price list. That is kind of hard to do when you don't have spammer's return address. Implied contracts have been commonly found non-binding by the courts (a typical example would be to open a cafe, wait when people walk in and then tell them "our admission fee is $100 -- please pay up, or we call police"). --vadim
