ISPs Warn Europe — Website Blocks Don't Work 210

Mark.JUK writes "The European Internet Services Providers Association has today warned the European Union that plans aimed at tackling online child sexual abuse content, which propose to force ISPs into adopting mandatory website blocking (censorship) technology, will not work because such methods are easy to circumvent; an ISP might cover your eyes but anybody can still take the blindfold off. Instead the EuroISPA has called for members of Parliament to consider permanently removing Internet-based child sexual abuse content at source, although this also runs into problems when the servers are based outside of your jurisdiction."

    EU: You say it's impossible? Pick one: do it anyway, stop being an ISP, or go to jail. Also, you get to work out the implementation and we get to determine if you're doing it right.

    • We have implemented a filter. If someone goes around it - too bad, but we have done what we can.

      It's nothing new, channels for illegal and immoral information will find new ways all the time. It's like trying to block wasps entering a beehive.

        Here's the problem I see -- it's not that blocking sites is infeasible and ineffective, and it's not that an ISP can't do it anyways, because they can. The problem I see is that when/if an ISP does implement a censor, no matter how ineffective, it will be abused and legitimate content will be blocked for legitimate users. Child porn will still be out there, and the people who participate in that industry will at best be inconvenienced -- it's the legitimate content that accidentally or maliciously gets caught in the crossfire that concerns me. The potential for good approaches zero, and the possible harm is non-negligable. This is why it shouldn't be implemented.

      If I point a gun to your head and tell you that I will kill you if you don't jump over the moon, that still doesn't mean you will jump over the moon. Bypassing any blocks by an ISP can easily be bypassed.

      Using DNS to assign bad sites with fake IPs? Use a different DNS server, any DNS server outside your country. Takes about 1 minute to setup in Windows, or install your own DNS server on your desktop, which will take about 10 minutes. Blocking IP addresses wholesale? Use a proxy server. Slightly slower, but bypasses any block by the ISP in seconds. Deep packet inspection? Use https. The point is that anyone that even remotely wants to bypass the "security" setup by the ISP can, with very little effort. If you don't remove the source (and all mirrors) of content, it is virtually impossible to prevent access to it on the net. Even China can't, and heaven knows, they are trying.

        Serious answer:

        They can't do it in China. The filters (mostly) prevent people from accidentally finding the things that The Party doesn't want them to see. It's pretty easy for anyone in China to work around the filters if they want to. It's also quite easy for the state to identify people who are making an effort to bypass the filters by their traffic patterns. If they're considered a potential threat to the oligarchy, they can be visited in the middle of the night, taken away from their homes, and shot.

        Without implementing the last step, the system wouldn't work. If you can find a politician in your country who wants a secret police with this power, then I suggest that you remove him or her from power by whatever means possible, as soon as is feasible.

    No one proposes banning pawn shops and second hand shops just because these are used by the criminal element to fence stolen goods. Legitimate businesses or structures are sadly used to illicit ends. You deal with crimes as they happen, not try all manner of questionable laws that infringe on civil liberties in the vain hope that somehow you can prevent crimes from happening.

    The only thing filtering will do is catch the more inept child porn producers and consumers. The smart ones have a command of the technical aspects of the networks they swap their foul evil on. The best we can hope to do with child porn, like any criminal act, is create savvy enough investigators to catch and prosecute them.

      • 2257 [wikipedia.org] was well intended in the US, but it had some serious flaws to it. For one thing the compliance statement was at the bottom of the page, requiring you to load an entire page of possibly illegal photos in order to check the statement. If you wound up on an index site, good luck figuring out which images if any were illegal. And the records requirements were really tough to comply with.

        But, there was some assurance that you wouldn't be thrown in jail for looking at a 2257 compliant site. Unfortunately

    • Most pawn shops do have to enter the seller's ID and the item description into a database for police. Once we get our "internet IDs" some advanced filtering might be able to recognize the contents of each data transmission so that the parties involved can be charged with the appropriate crime.
    • by brkello ( 642429 )

      Your analogy is terrible. Pawn shops have to follow the law or they will be shut down. If they are knowingly selling illegal goods, they will be shut down. Analogies are only useful when trying to explain a difficult concept. This is not one of those cases. The government wants to stop child porn. They propose a technical solution which isn't feasible and places the burden on the ISP. ISP complains it isn't feasible. Pretty simple.

    • The problem is jurisdiction. If the content is hosted in another country the only thing a police force can do it report it to the local authorities and hope. Beyond that, they do have control over the ISPs, so that's who they try to regulate.

      I don't see the problem with just purging those sites from the DNS servers within local jurisdiction. That should cover ISPs plus Google. The stated goal of the filters is to prevent well-intentioned people from accidentally stumbling across illegal content. DNS poisoni

        1. The ISPs don't want to be charged with a list of child porn sites, something so dangerous that to even look at it could get you jailed.

        3. Some blocks would be over-broad. Sites that host more than one site under the same DNS name. The same problem as IP blocks, from the different direction.

      I was under the impression that pawn shops and second hand shops have to at least try to make sure that the stuff they are getting is not stolen. You can't just turn a blind eye and act as a fence.

  • Surely the only answer is for ISPs to simply flag-up a warning with a 'Do you wish to Continue' button when someone tries to access a child-porn site, but do not block them. The Police know where these sites are, and can presumably log who goes there, with the assistance of the ISPs. This way, innocent surfers will be able to avoid these sites, but the visitors would be logged, and can face the consequences.
    • More and more ways to put your neighbors with open/WEP APs in trouble.

    • The problem is identifying those sites. You generally don't have to worry a lot about major pay sites, but the smaller sites and the free sites are a different matter. Establishing the age of the individuals is really the hurdle. It's often times not any easier for law enforcement to determine that the individual is 15 rather than a young looking 18 year old.

      • And note that in that case, you don't even get to know the obvious ones are illegal until after you have downloaded and looked at them... or at least looked and left them in your browser cache.

        I suppose you could report them, but I imagine most people wouldn't want to risk drawing police attention themselves in such a way. It might result in their computer being siezed as vital evidence, which could turn up other crimes. Best to just delete throughly and pretend you never saw it.
        • I wouldn't. I know the FBI wants you to report it if you accidentally download child porn. Personally, I wouldn't, I'd immediately wipe the image from the hard drive with a secure deletion utility not to mention the browser cache and all free space on the computer.

          Remember the US doesn't have a mens rea requirement for possession of child porn, so you're more likely to be turning yourself in than helping them deal with the real criminals.

    I call this bullshit.

    Look at banks. When a fake bank site goes up, it only takes hours sometimes a few days for it to be taken down after it was asked. Anywhere in the world.

    But it is probably better not to take the site down, but to collect IP-addresses and so on anyway.

    • Yup, that's pretty much the case. So one has to wonder why.

      How about sites that offer a service that is "illegal" (or just "unwanted" in a country) but legal in the country where the server is positioned.

      Hint: Think beyond child porn to solve this.

      No, any ISP-level sex blocking should pass the legal porn test. Which also means it's almost impossible to block it automatically, that's why these filters are planned to use manually updated (and probably secret) blacklists.

      • You know, it's probably easier to just ban porn, then you don't have to worry about that. Won't happen because despite all the prudish social expressions, Americans like us some porn. It's been a real problem for people that want it banned, but I'd hazard a guess that only a fraction of the people who claim to hate porn in public aren't secretly sneaking a pick in the privacy of their own home.
      • Probably secret? It's a list of the top child porn sites on the internet. Of course it'll be secret. Plus that means that any embarassing mistakes will never come to light, too. Espicially if the filter works by returning a false 404 error or just dropping packets, so it isn't readily apparent that the site was deliberatly blocked at all. The most effective censorship is the type that is never even discovered.

    No, it doesn't. This is the argument the proponents of filters are putting forward all the time. They've smartened up since we sunk their ship last, and are now claiming their goal is to "only block where we can not delete".

    Well, that would be nowhere because for a year now we've been asking them the same question, and they still haven't provided an answer: "Where in the world would that be?" It turns out that child pornography is illegal in every country on earth that has any Internet infrastructure worth mentioning. An especially naive and dumb politician here in Germany threw out a few country names when the debate started, and was quickly proven wrong in addition to receiving angry comments from those countries ambassadors. Then she tried a stupid trick, claiming that in some countries (again, names were named) there was no law against child pornography. She was technically correct - the muslim countries she had mentioned consider all pornography to illegal, punishable by death, so there is no specific law mentioning children.

    This whole campaign has been lies and bullshit on the side of the proponents from the start. I have yet to hear one argument from their side that is not a lie. However, they aren't dumb. They know how to play the public. They tested the waters and found them hotter than they had anticipated. But their current campaign is lot more "reasonable". In a debate, they stand a great chance of being able to convince Joe Public that they have a moderate POV that takes all eventualities into account and only wants to reserve the most drastic measure for the exceptional cases, but those freedom hippies they are the extremists and refuse to consider the possibility of evil, evil people abusing children by the thousands.

    So, remember, even the "block what we can not delete" is not a balanced position, it is a strawman. The only reason that the police here in Germany does not currently contact providers outside of Germany with a simple notice "hey, you are hosting child pornography, did you know that?" - which according to tests done by an NGO last year leads to a 95% takedown rate within a week, and a 100% takedown rate within a month - is that they are not allowed to do so. Not allowed by whom? Take a guess. Yes, that is right, the same people that need their "inability" to act so they can push for "block where we can not delete".
