AOL Blocking Spammers' Web Sites

Nuclear Elephant writes "According to this article, AOL has decided to take a fresh approach to fighting spam and is now blocking the spammer's web address. The philosophy is, if the customers can't visit spammers sites, spammers will not be able to make any money. On a side note, I suggested this concept about six months ago but nobody thought ISPs would adopt it. Now perhaps we can get a group like NANOG interested in sponsoring a blacklist for spammer addresses?"

      I too am concerned about the potential for abuse of a web site black list. I'm also concerned that AOL did not inform members of this change. Any ISP that implements a web site black list should redirect browsers to an HTML page that explains that the web site address is associated with known spammer. The user should then be given the choice to procede to the site or abandon the attempt. The black list should also be transparently available to the Internet community. Last, but not least, there has to be a clear policy for appealing a listing to allow for reporting of incorrect listings or other abuses of the blacklist.

      I'm sure AOL won't block any joe-jobbed targets but only bulletproof servers hosted at Chinanet, Telecom Malaysia, Procergs.com.br etc. which have been spamvertised by known spam gangs.

      This is *really* a good idea - Alan Ralsky uses several "throw-away" domains per spam run, but only a handful of different servers to host his crap. Null route these and Ralsky can enlarge his own penis.

      But in this case we're back to square one - we're already fighting KNOWN spammers like Ralsky...

      There's nothing new in that. But do you seriously think, AOL will pay dozens of employees to find out just WHETHER a spam is "legit" (in the sense that it's really advertising the target site) or "fake" (in the sense that the real goal is to get the target site blocked)? This will become some seriously tough piece of work!

      And it's kind of doubtful, whether it will help or not.

      Also - surfing TO a website just to find out whether it's a spam site or not is nowadays also giving away WHO is doing the surfing. By now I get more and more spams that have my email address encoded in the host names of the target site, e.g. the first part of the host name http://sx1piznvxr0svy.froidnet.com/
      sx1piznvxr0sv y is beh@icemark.ch (a replaced with z, b with y, ..., y with b, z with a, 0 with @, and 1 with '.' -- and the whole thing in reverse).

      So by now we are in a situation, where not just 'unsubscribe' lists are a way for a spammer to check the validity of our email addresses - no, even the host name we use to 'look at their "great" sites' give our identities away.

      It'd be really great if some people would finally clue in that the more successful spammers are actually pretty smart as well! (unfortunately for us though)

      Right now I think the best policy is still the passive filtering of incoming spams.

      - Filtering destination sites will open doors to abuse in terms of using fake spam to block unwanted sites...

      - automatic downloading of spamvertised sites will confirm which addresses are "good".

      The latter idea MIGHT still be workable, since the spammer will also get to know WHO has spam-scanners installed (provided the automatic download of the page actually has the name of the spam-filter in the User-Agent header field of the get request). That way the spammer would also be able to drop email addresses blocking his sites.
      On the other hand, this has one very big issue with it - if the spammer filters out these addresses for his sales, he could at the same time COLLECT these addresses for DDoS uses...

      No - PASSIVE measures are the only GOOD solution we have. Spam-Filters in addition to tar-pits slowing the the spam delivery...

      Everything else will - as sad as it sounds - open way to many doors to abuse!

      Having an advertising / services based website is hardly against anyone's (reasonable) terms of service, and ISP's have made it a point to be common carriers, ignorant of the content they are providing. IMO, it's not up to the ISP to decide whether services being advertised on a site are in their customers' best interests.

      You can't block these guys by IP, we already know that successful spammers have networks of infected zombie slaves, they'll use this network to host their website. Blocking by domain name has its obvious shortcomings also. How difficult would it be for a spammer to set up an IRC channel that advertises this week's (or today's) IP address and port number for accessing their spam contact page.

      Or maybe they just send a spam out every 12 hours with a new IP address advertised. They could just put their current IP address on the bottom of every spam they send, or in the headers.

      No, the solution proposed here is simply another speed bump for any determined spammer, and as lucrative as spamming turns out to be, it won't be long until all that's happened is that netizens have unwittingly (and happily) given up another net liberty in the form of website censorship.

    These are the same concerns people are having with FFB (Filters that Fight Back) which are capable of creating massive DoS's against a spammer, but don't really affect anyone else. I think blocking is certainly a step in the right direction, as it conserves bandwidth rather than consume it. AOL will definitely have to keep on their toes to make sure a legitimate website isn't blocked. Some of this can be automated, though - every time it thinks about blocking a website, crawl the site and perform the same type of language classification on it that you would a spam. The website should be even spammier than the email in most cases, or at least provide enough information to classify it as a spammy website. If it doesn't, throw up a red flag and let someone manually review it (or just drop it completely). The great thing about this function is that it not only blocks the spammer's method of contact, but it also makes it much more difficult for a spammer to move around. It's easy to use a different IP to send the spams, but to change your website every day or two is a bit more time consuming, and hopefully will exhaust spammers.
