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?"
You don't. The Internet never forgets, never forgives.
When do I clean addresses and domains out of my filters? Usually never. It's just too much trouble to keep tabs on all of them and actively look for them being cleaned up. Once they're in the filters, there they stay until something happens to make me take a look at them. Usually that something'll be someone I know getting caught by the e-mail filters and contacting me out-of-band to find out why I'm not responding to their mail. Or it might be me trying to go to a site I added to the filters ages ago and being blocked when I know it should be clean now, and I go and find it and remove it. But generally, unless something like that motivates me, I've got better things to do with my time than keeping track of all the bad guys I've run across over the years and whether they've mended their ways or not.
As the purchaser, you probably can't. But what you can do is demand that your provider move you to a better IP neighborhood, or renegotiate (read: "tear up") the contract.
Blocklists aren't about playing whack-a-mole with spammers, they're about disincentivizing spam-friendly providers.
If you're an ISP or hosting provider, and you harbor spammers and botnets, the IP ranges you hold are permanently devalued. That means it's harder for you to get customers, more expensive to support your legitimate customers, and your business, when you decide to sell it, is worth less than if you'd booted the goddamn spammers off your network when you had the chance.
Car Analogy: If you're doing your own oil changes, and instead of hauling the waste oil to a recycler, you dump it into your backyard, don't complain when you try and sell your house and the highest bid still leaves you $100,000 underwater on your mortgage, or requires you to spend $150,000 remediating it. Your property is worth less than it could have been, had you only been a better steward of it.
Why aren't the cops there getting customers lists from McColo and going after the fraudsters?
Because the police are far too busy going after the real criminals to waste time with legitimate fraudsters.

isnt THAT the slum of the internet?
Everything should expire after a year.
I also would suggest this in government. That all laws get renewed to automatically expire after 10 years. That way we can keep the law makers busy keeping the good laws while letting the old ones die, as well as keeping them from making crappy new ones that won't survive a 10 year renewal.

Among antispam industry professionals (yes, I am one) the term blocklist appears to be slowly displacing blacklist as the term of choice.
though I would like to see ARIN report a list of freshened addresses (with purchaser approval of course), with digital sig and time stamp, so I could fix my blacklist.. I dont see any easier feasible way to proceed.
