And before anyone starts to give me any guff about being soft on spam -
I've been known to nuke accounts, and not bother asking questions. I chased down the Empire Towers group and helped put an end to them. I spent 18 months cleaning up the -very- tarnished reputation of a now bought out web host almost 10 years ago, and have the scars to prove it. I hunted a spammer down and ratted him out to his own mother in Vancouver, BC, Canada.
The news regarding Ralsky had me drop a shot in celebration.
Believe me - I -detest- spam. At the same time, the methods utilized by SORBS were ineffective, and most legitimate hosts and providers stopped using them years ago.
Selective DNSRBL systems, as a practical method, WORK. Blocking residential cable from sending email? Hella good idea, for example. Blocking known dial-up ranges, as well. Blocking webhosts in an attempt to get their customer base to force them into canceling contracts that may cost the web host hundreds of thousands, if not millions of dollars? Nuh-uh.
When 'collateral damage' was useful, losses MIGHT have hit 10k. Now? Talking millions? Businesses will buy a new IP block and move the affected customers, and call it a day. Especially if they're blocked not because a customer has been an idiot, per se, but because the customer was hacked and used as a bot.
So, yeah. Rock on with your bad selves.
