The service manages pseudonyms, which are intended to be used out on the web in some way. But the service can't tell if people are playing nicely or not. The only way this could happen is if the service receives *complaints*. This is the only feedback mechanism possible. I gather that Tor does in fact send out complaints about people who misbehave. Perhaps blog services do so as well. One problem is that these complaints generally don't arrive in real time. It takes time for a human being to notice that some vandalism has occured and register a complaint. If the pseudonym service is going to be able to respond, it has to know which pseudonym was active at the time the bad actions occured. Jimmy Wales very accurately describes the problem with pseudonyms at the web-server level. If Wikipedia or blog comments require the use of pseudonyms, these can be linked after the fact. I am very sensitive to this problem myself. The implied solution is that the pseudonym service would maintain the pseudonyms, but would not reveal them to the web service. Rather, it would only provide a certificate that the pseudonym is currently in good standing, i.e. it has not received (too many) complaints. This implies that the pseudonym service must maintain a record of recently used pseudonyms, and have some way of mapping them to what the web services (which issue the complaints, services like Wikipedia) would have seen. This mapping might be by IP address, or if Wikipedia and other services are willing to do more, it could perhaps be an opaque identifier which the pseudonym service provided at the time the web service (Wikipedia) asked whether this pseudonym was a "good guy" or not. As a specific example, the pseudonym service might have replied, to a query from Wikipedia, "Yes, this user is a good guy, and the sequence number of this reply is #1493002." Then later if abuse occured, Wikipedia (or the blog service, or other victim of vandalism) comes back and said "we had a problem with the user who was certified with sequence number #1493002". The pseudonym server would map this back to the pseudonym in use at that time, and invalidate the pseudonym (or at least give it a bad mark, with enough such marks killing the nym). The main problems with this solution are first, it requires considerable manual work on the part of the pseudonym server, similar to the work necessary at an ISP to resolve complaints about users. It could be a full time job. And second, it requires custom software at Wikipedia and other web services that might be willing to work to implement such a solution. The second problem could be alleviated by the use of a related service, a web proxy that is only for "good" pseudonyms. The web proxy would provide transparent pass-through similar to anonymizer.com, but only for users who were able to provide the kind of certification described above, from the pseudonym server. In this way, the outgoing IP addresses belonging to the web proxy would be "good" from the POV of Wikipedia and other web services. Those services could continue to use IP blocking as one of their main tools for handling misuse, treating the web proxy service as being like an ISP. The web proxy service could be bundled with the pseudonym service, or they could exist independently.

I'm not an expert in Tor-ish matters, and so despite my strident manner at times, I am very happy to learn more and understand why some initial suggestion I might have has already been considered and rejected with good cause. And as an ongoing gesture of goodwill, let me explain _why_ I want Tor to be significantly less effective as a tool for Wikipedia abuse. It isn't because Tor is a threat to our work. One of the nice things about how Tor is implemented is that we can easily get a list of the exit servers and block them. Problem solved. No, the reason I am interested in exploring possibilities for reducing the abuse is not to protect wikipedia, but to make it possible for Tor's goals to be achieved more effectively. > {1} To be clear, I think that it's more accurate to talk about changes > to the User/Tor/Wikipedia interaction, and to suggest a need for > action by the Tor project and its supporters, than to talk about a > need for changes in Tor's architecture, and a need for action by > Tor. Yes. The one thing I should caution against, though, is assuming that the right solution to the problem should involve anything complicated on the part of Wikipedia. We're willing to do whatever, but I'm also interested in how this problem can be solved more generally. In this way, tor servers can be allowed to post anonymously and in a hit-and-run fashion to blogs, for example. --Jimbo - End forwarded message - -- Eugen* Leitl http://leitl.org";>leitl __ ICBM: 48.07100, 11.36820http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE signature.asc Description: Digital signature

As someone posted, Tor does not prevent people from using pseudonyms. If pseudonyms will solve Wikipedia's problem, then fine; a good portion of this argument has been about Wikipedia's need for authentication. See my comments following your footnote. > Wikipedia has user accounts and IP-based blocking. That's a kind of > authentication.

That's a lack of authentication. > Now why couldn't *he* say that? The man's involved with an encyclopedia project; he should be able to write. The way this particular aspect of our disagreement arose is that I accused him of wanting Tor to do his authentication for him. He claimed that Wikipedia does do its own authentication. Now you explain that Wikipedia does not *require* authentication. Which undermines the usefulness of offering authentication. > It's like how Tor blocks some highly-abusable services, like SMTP on > port 25, but doesn't do content filtering to try to hunt for abusive > behavior on exiting streams.

An anti-Tor > rhetorician could say, "You filter abuse, but you don't filter abuse!" > But what would that prove? You are attempting to compare Tor's security policy to Wikipedia's security policy. Tor has a security policy. Tor's security policy is to protect originating IP addresses which might be connected to persons. We hope, in combination with Privoxy, it protects anonymity reasonably well. On the reasonable (I think) premise that other sites are primarily responsible for their own security, it only limits some abuse. Now, what is Wikipedia's security policy? With no authentication requirement, and a policy that allows anyone to edit (unless they're connecting from a blacklisted IP address), I might as well ask, "What is truth?" > {1} This case is more commonly known, in the literature, as > pseudonymous communication than anonymous communication. Then > again, if you're going to invoke dictionaries in a technical > discussion, anonymity becomes a very broad term. But Tor is about anonymity. Not about pseudonymity. Not about other forms of authentication. As it should be. >From a communication perspective, anonymity has a very specific meaning. It means we cannot identify a person. Note that the failure to identify a person makes no reference to kind of identification. There need be no preference for "real life" names versus pseudonyms versus IP addresses versus whatever else you can think of. Anything that identifies a person contradicts the concept that this person is anonymous. This has practical implications. For instance, as someone pointed out, when the Chinese police raid a dissident's apartment, and search his hard drive, they are able to tie the pseudonym to a "real life" identity. If the police can also connect the pseudonym to what they consider "crime," the distinction between a pseudonym and a "real life" name loses much of its value; hopefully, the pseudonym permitted the dissident to continue his activities for longer. Now, I will certainly agree, as someone else pointed out, that Tor should permit the use of pseudonyms or other forms of authentication. But the fact remains that any identification--as implied by authentication--contradicts anonymity; it is therefore something which Tor should not involve itself with. Simply put, it is not and cannot be Tor's problem. -- David Benfell, LCP [EMAIL PROTECTED] --- Resume available at http://www.parts-unknown.org/ - End forwarded message - -- Eugen* Leitl http://leitl.org";>leitl __ ICBM: 48.07100, 11.36820http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE signature.asc Description: Digital signature

I think I've identified one of the reasons some people here are disturbed about your suggestions. When you talk about changing the Tor architecture, they think you mean changes to Tor that would require all users to have pseudonyms, or ostracize the users who didn't. When you say "Tor should do X," they think you mean "the Tor software should do X".{1} If that were what you meant, they would be right to be concerned. Pseudonymity is wrong for many users. Complicating the core Tor implementation would be bad. But these aren't your goals, if I understand correctly. Wikipedia doesn't ultimately care how Tor is implemented, or what it contains, so long as it is significantly less effective as a tool for Wikipedia abuse. Yes? This could be achieved, as some people fear, through modifying the core of Tor. But that isn't the only way to change matters. As discussed, introducing a separate pseudonymous authentication service (perhaps even an anonymous credential service, if we can find a way to do this without patent infringement) would serve just as well, and require no modifications to the Tor code. Users who didn't want to use such a service would be no worse off than they are today. Users who wanted to use Tor and edit Wikipedia at the same time could decide whether the implications of such a service were acceptable to them. {1} To be clear, I think that it's more accurate to talk about changes to the User/Tor/Wikipedia interaction, and to suggest a need for action by the Tor project and its supporters, than to talk about a need for changes in Tor's architecture, and a need for action by Tor. yrs, -- Nick Mathewson - End forwarded message - -- Eugen* Leitl http://leitl.org";>leitl __ ICBM: 48.07100, 11.36820http://www.leitl.org 8B29F6BE: 099D 78BA 2FD3 B014 B08A 7779 75B0 2443 8B29 F6BE signature.asc Description: Digital signature

I think that we can agree that there are short-term and long-term solutions to this problem. In the short-term, we can block Tor nodes by routing address and develop special mechanisms to allow Tor users to edit Wikipedia content anyway. We can do this either via some sort of indirection or via some sort of special change to Wikipedia itself, working around the limitations in Mediawiki. We can focus on the short-term for now. However, I think that most proponents of Tor believe that in the long-term, Wikipedia should support location-independent users. So we need a plan going forward, and this plan should be sufficiently general to apply to any location-independent users, not just users of Tor. I think that many of us hope that some day the Internet will be flat and routing information will be useless in tracking identity or reputation. This will be difficult to achieve, but it is certainly my hope. As such, I am loath to encourage the design of systems that require any form of access control at the network layer, and I believe that the right thing to do is avoid such temptation, even if software tools like Mediawiki appear to be designed with network-layer access control in mind.

This is getting close to the 'agree to disagree' point, but I'll go one more round. No, the transport layer is not to blame. The malicious users are to blame. The subset of Tor users abusing Wikipedia may be "almost universally bad", but that is still a subset, and doesn't indight Tor itself. > If what you're saying is "I think it is fine for Wikipedia to block > Tor," then you really aren't contributing productively to this > conversation.

That anonymity is at odds with the social contract where it provides an avenue for malicious action without responsibility, but that fact is not the fault of the anonymity or its enablers; it is the fault of the bad actors. > We are not looking for a perfect solution.

I'm not saying openness is wrong. I'm saying it has its costs, which you obviously already recognize, and reducing those costs may require embracing a less-than-fully-open philosophy. That modification may include blocking Tor exit nodes, based on the behavior of bad actors. That's unfortunate, but expedient. But trying to force-fit pseudonymity on the Tor anonymity model is an attempt to shift your costs onto Tor. > > Roger gets it. The Wikipedians don't. > > What is it that we don't get? That Tor is working as designed, and that the problem with bad actors using its cloak is a problem with the actors themselves. As Bob Hettinga noted elsewhere, "perfect pseudonymity *is* perfect anonymity". Arguably, perfect pseudonymity is a more useful construct, but it is a much harder problem than anonymity. And given that perfect pseudonyms are perfectly disposable, that still won't address the bad actor problem completely. Openness requires responsibility, and responsibility implies accountability, so the only "perfect" solution is 100% meatspace correlation to enable enforcement of the social contract. That might solve your vandalism problem, but it introduces other issues. > This thread started off because a Tor > server complained to me about the blocking, and part of my response is > that one beef I have is that some people in the Tor community seem very > happy to simply stick their heads in the sand and pretend that > "Wikipedians don't get it". > > That's not helpful.

Wikipedia should allow Tor users to register Wikipedia nyms. Then they could block: Tor users trying to edit without a nym; Tor users trying to edit with a nym that has a bad reputation; and they could rate-limit Tor users trying to edit with a nym that has insufficient history to be classified as good or bad; while not blocking Tor users trying to edit with a nym that has a good reputation. This will require some changes to the MediaWiki software that Wikipedia uses. AFAIK, there's currently no way to rate-limit nyms that have insufficient history, and blocks on IP addresses are currently all or nothing. --apb (Alan Barrett)

I don't know how much more clear I can be about it. Because Tor users are almost universally bad, because almost no good edits come out of the Tor network, we block them.
