my case, it was a /24 that was blocked (mixture of dialup, dynamic dsl, and static). My query for info resulted in the /24 being unblocked, then later a trojaned customer spewed spam and got the /24 blocked again.
Having proper rDNS and if possible suballocating dialup / dhcp and static ip pools would be a good idea, so admins can tell these apart when they are applying ACLs.
This was repeated a couple times, apparently. It might have been better if I had specifically requested unblocking of just the one IP in there that actually runs a mailserver - it likely would have stayed unblocked.
That too is a good idea.
