If you remember that article from the Oregonian about a spammer talking 
about his business, he mentioned that spammers operate all kinds of clubs 
and chatrooms where such software is discussed and developed. The only way 
to obtain this software, is for someone to find a cooperating spammer (like 
that's going to happen!) or "infiltrate" these clubs acting as a spammer. 
That requires time and effort, and all of us are working people with not 
much of that going around. The spammer discussed in the article was 
unemployed I believe, and had plenty of free time.

Nevertheless, if anyone possesses or has any type of spam software, please 
come forward.
