They lists IPs that are sources of spam.
Um, I am pretty sure that it is not 1995 any more. There are zillions of blocklists, most run pretty badly. The ones that people really use, like the Spamhaus ones, are run very conservatively and only list IPs you can block with a very low chance of losing mail your users want. By now it should be evident that blocking spam sources one mail system at a time is not going to affect anyone's behavior. Spammers complain when Spamhaus lists them, but that's because half the world uses them, and that in turn is because you can use the XBL and not lose mail you want.
