Recovering the Slums of the Internet?

turtleshadow writes "Brian Krebs of the Security Fix Blog analyzes the McColo Spamming one year later and asks an interesting question: 'How does one renovate and recoup the lost trust to the slums of the Internet and reclaim back all the domains and IPs that have been blacklisted?' Indeed, the economic benefits abound when a huge swath of illegal and annoying activity ceases — but given the basic design of the Internet, what happens over the long run to IP space and DNS when hosting companies come and go and vary in their trustworthiness? So too, now Geocities is dead [as a business], but does that still live in your filter list? It still appears in OpenDNS under several policy categories. How, in a few years, will I tell if some Hosting/Colo sold me Whitechapel Road/Ventura Avenue for Mayfair/Boardwalk prices, and no one is going to accept my mail from a former slum? When do you, if ever, roll back the blacklists and filters for 'dead' threats and spammers?"

My problem with that is when you get reassigned IP space from a spammer. My host aquired a block from ARIN, which used to host russian servers. Well these russian servers were apparently spambots because I just recently found out yahoo does not accept mail from any of my servers. This is a major problem and jumping ship to another host does not guarantee this problem will go away. I had no clue who to contact and ended up requesting new ip space from my provider... but that caused a world of pain for my customers.

I used to think my old boss was crazy when he said he never wanted our antispam solution to rely on any blacklist provider and it didn't really sink in until I was on the opposite end of the spectrum. Blacklists are bad.
