If they kept logs and were able to tell us which IP address in the /24 sent abuse to their network we would then be able to investigate it. Their stance of 'it's coming from your network you should know' isn't really helpful in solving the problem. When an IP is blocked a lot of ISP's can tell you why. I would think when they block a /24 they would atleast be able to decipher who was sending the abuse to their network to cause the block and not simply say 'Were sorry our anti-spam measures do not conform with your business practices'. Logging into every server using a /24 is looking for needle in a haystack.

*heh*  And yet just last year, Yahoo was loudly dennounced for
keeping logs that allowed the Chinese government to imprison
political dissidents.  Talk about damned if you do, damned if don't...

I guess logs should only be kept as long as they can only be
used for good, and not evil?
