To answer your immediate question, you cannot - practically speaking - tell what content is stored on your computer specifically. Doing so requires a concerted effort and the use of tools that could - but to my knowledge do not - exist. Even then, you would be unable to identify everything. You can remove the content Freenet has stored on your computer by uninstalling Freenet. Hasn't someone created some kind of chunk/CHK filter already? (For filtering local content?)

Of course, it would also severely compromise the anonymity of the undesirables (the people), which defeats the purpose of Freenet. Which is to say, it's not that it's technically impossible to do this, it's that we believe in free speech. Anyone is free to fork Freenet to only allow desirable content. Good luck. There are lots of problems with a blacklist: Unless they were a government agency it would be legally very difficult to maintain a blacklist, since they'd need to download the full metadata in order to block all the blocks, and probably they'd need to download the full data to check whether it is what it is claimed to be (which makes them vulnerable to prosecution for posession, not to mention various other obvious issues). Of course you could block stuff by downloading the metadata without checking it, but this would be easily exploited for censorship of anything you don't like. And according to EFF's advice, you'd probably have to block ALL illegal content, not just child porn. And anyone using the blacklist would have to trust the person who publishes it - especially as the blacklist would have to not include the full CHKs but only enough information to match them, without being able to decrypt them. A whitelist is possible maybe. But it'd have to be a separate network, and it'd be enormously, and dangerously, centralised. signature.asc Description: This is a digitally signed message part. ___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe

[freenet-support] content question
Hi. I read the FAQ question that says I don't want my node to be used to harbor child porn, offensive content or terrorism. What can I do? My question is, if I use freenet, how can I tell if my computer has such content installed on my computer, and how to get rid of it when I stop using Freenet? Thanks.___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe

To answer your immediate question, you cannot - practically speaking - tell what content is stored on your computer specifically. Doing so requires a concerted effort and the use of tools that could - but to my knowledge do not - exist. Even then, you would be unable to identify everything. You can remove the content Freenet has stored on your computer by uninstalling Freenet. If you are on Windows, there is an uninstaller. I don't know about OS X. On Linux one can delete the directory Freenet is installed in. More abstractly - as to why one's Freenet node could be used to store undesirable content. Freenet functions as an encrypted storage device distributed between the hard drives of all the users of the software. Instead of storing entire files, things are stored in encrypted pieces called blocks. When you use a key - they can start with CHK, KSK, SSK, or USK - the key contains information on how to find the blocks for that file and also how to decrypt the blocks once they are fetched. Without the key it is effectively impossible to tell what blocks belong to what files, or what those files are. Philosophically speaking, Freenet is a medium for censorship-resistant communication. As one would expect this means it is designed to be very difficult to censor or block, and contains no mechanism intended to remove objectionable content. From a technological point of view one cannot have free speech with exceptions. If a capability to remove objectionable content exists, that capability can be used to censor arbitrary content. Freenet is a tool, and some people choose to use it for things that are considered offensive or objectionable. In a sense, that they are able to do so demonstrates that it has achieved something of its goal. signature.asc Description: OpenPGP digital signature ___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe

What can I do? Did you? Because the FAQ quite clearly states that if this is not acceptable to you, you should not run a Freenet node. May I also ask why you are interested in Freenet at all, if you are so keen on information censorship? ___ Support mailing list Support@freenetproject.org http://news.gmane.org/gmane.network.freenet.support Unsubscribe at http://emu.freenetproject.org/cgi-bin/mailman/listinfo/support Or mailto:support-requ...@freenetproject.org?subject=unsubscribe
