Thank you Max for bringing this up. There is a lot of useful information here:

I am not an expert on spamming, as my field is related more towards scammers. however I have heard (as I previously posted) that the spammers were working on ways to defeat the anti-spam methods that people were working on.
After reading the Wikipedia article, I feel that we all need to be more aware and to help wherever we can those programmers who are working to stop spammers, hackers and scammers.
The amount of money obtained by these unethical acts can be very large indeed and can turn the heads of some administrators and programmers who actually support and encourage these hackers, spammers and scammers on their own websites and ridicule any who oppose them.
It is clear that the motivating force for the spammers to invest so heavily in automated programs is greed and "easy" money. It is scary how much these actions can rake in. And so there is a lot of money that can be used to increase the effectiveness of the unethical automated programs.
I think we all need to do what we can to stop the unethical and immoral guys in any way we can.
