Disqus Bug Deanonymizes Commenters

alphatel writes "The Swedish company Resarchgruppen has discovered a flaw in the Disqus commenting system, enabling them to identify Disqus users by their e-mail addresses. The crack was done in cooperation with the Bonnier Group tabloid Expressen, in order to reveal politicians commenting on Swedish hate speech-sites."

      Actually Expressen are not revealing the identifies of politicians who commented on expressen.se, they are revealing the identities of commenters on racist / xenophobic sites friatider.se and avpixlat.info. The articles and comments on these sites are mostly very harsh, distastefully racist, and written anonymously. They have identified very racist commenters as members of the controversial, Swedish far-right, and most would say racist, party Sverigedemokraterna. The SD-party works hard to portray a more polished image, with for example a "zero tolerance policy on racism", which equates to you might be kicked out if you say or do something too obviously racist. SD has it roots in the 90s far-right racist movement in Sweden (http://www.youtube.com/watch?v=LZWsZyShR_s), and one their mottos is "Sweden for the Swedish". The party is definitely mostly racist, but their official political stance is more xenophobic and social conservative, with a few immigrants joining their ranks complaining, for example, that it is the Somali or immigrants who are the "real problem".

      Researchgruppen used a Disqus security flaw to find out which e-mail addresses were behind some of these racist commenters, and are now revealing that behind the nicknames were SD-politicians. So.. This is a big win for Expressen, since the Swedish mainstream media and most Swedes are sworn enemies to Sverigedemokraterna.

      And on another note.. Congratulations to Flashback, the quite huge, Swedish, non-profit, ultra-liberal and quite lawless discussion forum, which has absolute free speech and therefore has become illegal to run from Sweden (it's now run from abroad). Flashback has through the years succeeded in keeping their users anonymity safe and freedom to speak total, no doubt without attempts form the Swedish state, police and media to the contrary - since flashback has become the main for hub for discussions about controversial subjects like drugs, racism and much more.

      These "racist" sites are the ones which post news without Swedish white pixelization and political correctness. However it is true that there are comments which are negative - just like comments in any media outlet.

      What Expressen and Researchgruppen did was that they de-anonymized their political opponents. They are also targeting people who have nothing to do with Swedish Democrats, just ordinary people who disagree with the nation wide consensus of immigration and do not want lose their jobs for expressing their opinions.

      As a Finnish citizen I am very worried of the state of democracy in Sweden. Swedish media is hell bent to destroy Swedish Democrats and they use any means. Swedish ultra left is extremely violent and seems to enjoy total freedom. It is not the ultra right or racists who do the majority of political violence in Sweden.

      Outing political opponents and making a illegal registers of identities breaks Swedish and EU laws. Harassing people because of this also breaks laws, anonymous or not, people have right to express their opinions in the network and ordinary citizens can not expect to be chased by the media or extremely violent political groups because of that.

      We Finns always joke how Swedes "Diskuterar" so much of everything but it seems we are little bit outdated on that belief. Swedish media do not want to have civilized discussion and extremist groups are using violence to advance their cause.

The US wouldn't even exist today if England had the ability to know everything that was being discussed in their territories. And yes, sometimes social progress needs heroes. People who are upfront about their beliefs in open disobedience. Sometimes we need martyrs. But social progress doesn't actually happen there. It happens at home, at the homes of the low profile individual.

In early electronic days when dialup was king, there were always phone records and one had to have accounts on bulletin boards, and systems like fidonet kept origination records. In the days of Usenet, messages could at least be tracked back to a newsserver of origin, and assuming that records were kept, the ISP information could be found and then the subscriber account could be identified.

    Because the hate speech goes underground, where there is no sense of the scope of the problem. So the government doesn't understand how big the problem is and unable to do an appropriate protection of the hated groups.
    Secondly there isn't a counter dialog going on to discredit the hate logic. So people get this feed of hate in private and told that it is taboo, so they keep it quite, however there isn't anyone pointing out the flaw in their reasoning. So they can create more people who hate.
