Bounces are used as validators in many cases. The sponsors 
buy these lists and they want some deliverability. It's
inevitable that a filter will get some, but that's not the
spammers problem. The method is the spammers problem.

You need to differentiate the sponsor
from the spammer. They are *usually two seperate entities
these days. Sponsor BUY$ the spammers services. The sponsor
is the scammer, seller, phisher, or whatever is the trend of
the day.

Let's call this the usual current hiearchy:

SPONSOR
   SPAMMER - High speed spam engine
     BOT HERDER - Gets the bots
      RBL VERIFICATION - Sells the quality measure
       BOT ARMY - Sends Spam
        LEGIT MTA - Delivers Spam
         RECIPIENT - Gets Spam

Oh. And they're all different people or machines. They
can be one, but they also can be many. Think $$.
