The World's Worst Spam Support ISPs
Spam continues to plague the internet because a small number of Internet Service Providers knowingly sell service to professional spammers for profit, or do not enough or nothing to prevent spammers operating from their networks.
The ISPs listed on this page knowingly provide service to spam gangs and ignore spam reports from anti-spam systems and internet users. They have been notified of each SBL listing on their network. These ISPs are defacto spam havens where spammers operate unhindered by the ISPs' administrators and executives. In the name of profits, these networks turn a blind eye to blatant spam gangs on their networks.
Although nearly all ISPs claim to be anti-spam, some executives factor revenue made from hosting known spam gangs into corporate policy decisions to continue to sell services to spam operations. Others simply decide that closing the holes in their end-user broadband systems that allow spammers access would be too costly to their bottom lines, or that the cost of hiring, training and tooling of a skilled Abuse and Security team is not worth the tradeoff in ISP reputation.
The majority of the world's Internet Service Providers succeed in keeping spammers off their networks and work to maintain a positive anti-spam reputation, but their work is undermined daily by the few ISPs such as these, who, out of corporate greed or mismanagement, choose to be part of the problem.
