LIke I said before Spamhaus and the other DNSBL providers aren't the villain because if I want to harm your opt-in mail list all I need to do is get the email addresses of a bunch of rabid anti-spammers and other nut jobs that add themselves to opt-in lists and then freak out when they actually get email and put all those people in YOUR opt-in list, who'll scream murder to Spamhaus and cause your customers problems.
It's the animals out there sabotaging others for their own gain, either as spammers, seding opt-in lists with anti-spammers, running botnets, criminals one and all.
I won't say Spamhaus and the other DNSBLs don't cause problem for legitimate people on a regular basis but they also keep my servers mostly spam free and running instead of clogged with garbage so deep nobody can dig themselves out. Collateral damage is a shame, some of it's the fault of the individual being blocked, but the needs of the many...
FYI, every now and then my FIL can't send email from Comcast to us because of my DNSBL settings and I'm sure his machine is probably hacked and sends the occasional spam LOL
