No.  Spammers never remove an address from their list.  What happens is 
that most spammers get a spam your self rich kit with their last few 
dollars, spam for a while and then discover that they are not recovering 
their investment they sent in to the "millionaire" spammer they saw in 
the media.  The money is in selling the spamming kits, not in sending 
the spam.  But only one print media has bothered to point that out.

Think pyramid scam.

There seems to be an unlimited number of suckers that will buy these 
spamming kits.

The best way is for you to reduce the spam you get is to convince your 
ISP to remove the spam infested network addresses from their list of 
acceptable e-mail sources.

If your postmaster will use open proxy DNSbls, it will eliminate most of 
the spam from all countries with out losing real e-mails.

If your postmaster will use a conservative dynamic list DNSbl it will 
cut down on a bit more.

If they use an aggressive dynamic list DNSbl like dul.dnsbl.sorbs.net it 
will eliminate quite a bit of spam with a small risk of blocking some 
real e-mails.

I see the most spam leakage and most complaints of lost e-mails from 
people who's postmasters primarily depend on content filtering to 
attempt to block spam.

I see the least spam leakage from those postmasters that refuse e-mail 
from spam infested I.P. addresses.  I see the fewest complaints about 
lost or incorrectly blocked e-mail from the users of the same postmasters.

This is the case even when the postmasters use DNSbls that are known to 
be aggressive in blocking spam.  After all they can white list I.P. 
addresses that they never want to see blocked.

It seems that many ISPs will not clean up a spam infested network until 
their paying users find that no one will accept their e-mail.

As long as ISP try to filter spam primarily by content and not by 
source, the spammers will win.  As soon as an ISP decides not to accept 
the spam from spam infested I.P. addresses, the spammers lose access to it.
