No, that is NOT the only way. We presume that the spammer had 8 dial-up
accounts. Who is this professional spammer, and how come he/she/it can
still find a provider? That is the question. Perhaps also who is the 
merchant that ordered the promotion?

The identity of such individual or company belongs on a black list.
Yet the spammer is able to subscribe again tomorrow, next week, next
year... and nothing happens to them. That is the point where control 
should be exercised.
