I agree, spamhaus has always been great.  

We were on a few feedback loops and did not show much for that subnet...   anyway solved now.    Got the ex-customer's other ISP to block the announcement since we killed it a while ago, also removed the SWIP.  ;)

You wont find me holding up uceprotect or apews as fine examples of
properly or even competently run lists, I'd point you to spamhaus for

But, in this day and age, and with the volumes of spam around, I'd
counsel you NOT to wait for or expect manual complaints to your abuse
desk, almost nobody does that these days.

Feel free to signup for AOL etc feedback loops and you'd probably get
a much higher volume of complaints - enough that you'd have to
dedicate an email address to it, and use the scriptability of the ARF
format these feedback loops are sent in, so you can get / generate

Periodic rDNS scans of your network, and either making rDNS requests
manual, or at least running periodic rDNS scans of your network to
spot that kind of customer would make sense too.  You must admit that
the kind of rDNS Steve Champeon posted in in that very long list
upthread sticks out like a sore thumb.
