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.

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

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.
