Combating abuse in Matrix - without backdoors (Matrix blog)

ThisMatrix blog entry describes a planned reputation-management systemthat, it is claimed, accomplishes some of the same goals as governmentbackdoors without the need to compromise end-to-end encryption."Just like the Web, Email or the Internet as a whole, there isliterally no way to unilaterally censor or block content in Matrix. Butwhat we can do is provide first-class infrastructure to let users (androom/community moderators and server admins) make up their own mind aboutwho to trust, and what content to allow. This would also provide a meansfor authorities to publish reputation data about illegal content, providinga privacy-respecting mechanism that admins/mods/users can use to keepillegal content away from their servers/clients."
