Magdalena Donea, a system administrator at Web hosting company KIA Internet Solutions, found a set of her company's IP addresses blacklisted recently on SPEWS. She successfully lobbied to get the listing removed, but it was relisted a second time with additional IP addresses, a move that also affected a company client, the Libertarian Party.
"The SPEWS system is unapologetic about false positives and even regards them as a plus. They've taken the 'ends justify the means' argument way farther than I've seen anyone else take it," Donea said.
"Their philosophy appears to be that if innocent businesses and individuals on the periphery of spam-house blocklists are affected, then those innocents will have no other choice but to pressure their upstream provider to remove the spammers from their blocks, thereby solving the spam problem bit by a bit. Draconian, yes. Effective? Sure."
