Good idea and I am sure lots of people will find the information useful. Cheaters suck but use the cheaters to your advantage. I have close to 5500 domains, over 150 IP addresses (or subnets) and 50 name servers banned on my humble little network. I don't plan to share my list either.
Why? Simple! Believe it or not, other sites are your competition. I don't go out of my way to help the competition if I can avoid it. My sites are fairly cheater-free (or more cheater-free than most). I actually get emails from surfers thanking me for having less redirects than most other sites. It pays to guard yourself against cheaters and it pays to keep your cheater list to yourself.
Free, useful tip from me to you. Don't get used to it. I don't make a habit of giving free tips to the competition.
