Subject: denial of service on ISN list

Bummer, ISP' not wishing to take responsibility for their spamming
clients, almost as bad as those ISP' that let compromised systems ride
their backbones while spewing attacks at the rest of the internet.  You'd
be better served to find an ISP that knowns how to play better with t;s
internet neighbors then whining here.

Thanks,

Ron DuFresne
