There is an implication of lack of fairness in this statement. Some ISP's ignore complaints about spam, because the spammers are paying for bandwidth and server space. There is also the issue of dynamic allocation of DNS addresses - which means that the address used by a spammer now is not the same as used 10 minutes ago, or in the future. Either way, blocking the entire ISP puts pressure on the ISP to clean up, as they otherwise stand to lose all of their legitimate well behaved customers. Kind of like a neighborhood citizen's group boycotting a retailer in order to force certain goods either onto or off of the shelf. “For example, some DNS blocklists will list an entire block of IP addresses belonging to a given site, even though only one of those IP addresses actually was associated with the underlying spam.”
