      Women posting hashes of their abusers names is a brilliant way of finding others until you have critical mass to come forward. It's the kind of thing cyberpunk stories about crypto would have contained had the genre not been defined by men.https://twitter.com/sarahjeong/status/943941331583299585 …

      Women keep asking me if anything will actually change after Weinstein. I always say yes, if only because infosec, of all fucking things, has changed. https://www.theverge.com/2017/12/21/16807116/infosec-community-sexual-predators-weinstein-assault …

      A great many men have been up in my mentions pointing out that men can easily search a hash of their OWN names to identify women who are posting. Guys. Bros. Dudes. Abusers are ALREADY aware of the people they've targeted.

      And for the "but Rainbow tables!" crowd... What if I told you that the goal of women posting hashes of their abusers names actually has nothing to do with protecting men? It's about not having to be the first one to speak out.

      You still don't get it. I know that's the goal. It doesn't matter what your goal is. If the hashes are reversible, *whatever your goal is* in using hashes can be subverted. You might as well just post plaintexts.

          “Can” is *extremely* relative. It’s technically possible to invert a hash given given sufficient resources, but it’s definitely *not* the same as posting plaintext. There’s also some plausible deniability in that usually there are collisions.

          I wonder if it might help for different posters to use different hash functions, so if one person has targeted multiple people, their name can be triangulated on because it will very likely be the only one in common between the possible plaintexts of different posters’ hashes.
