Comment Responsibility goes both ways (Score 1) 218
Yes, ISP's need to be responsible and take action against spammers, and yes, ISP's who continually fail to do so on a significant scale over a long period of time are fair game to block, but in this particularly instance it sounds like Spamhaus's actions may have been abusive and rather arrogant. I use Spamhaus's blocklist myself, but organizations like Spamhaus and Cisco SenderBase need to take some responsibility to ensure that they are not unduly effecting legitimate businesses and networks. Taking large-scale blanket actions that effect many legitimate sites undermines the anti-spam industry as a whole, because it makes it more difficult for people to rely on anti-spam products/services.
