Digital Harassment / Doxxing

Security Culture

  • What is Security Culture? — Zine compiled by the Sprout distro for activists
  • Basics of Movement Security — Book created from the author's workshops. The phrase "movement" is vague here, but the book has a lot of specifics about "combating the 'political police' or state security agencies"
  • Dulles Rules — Informal rules of spycraft for the US government. Interesting and odd

Safer Spaces

This section is not a formal code of conduct, but a couple comments: We approach security as an emotional issue, not just a technical one. We want people at our workshops to come away with concrete steps they can take to make themselves be and feel safer, overall. To do that, we all need to be able to talk about our experiences, fears, and priorities freely. And that can only happen if people feel that they can speak without fear of getting shutdown or shamed for their concerns, or that they will be recorded in some way that they did not expect. For those reasons, we will interrupt or stop any kind of speech that demeans another workshop attendee, which includes sexist, racist, transphobic, ableist, or technocratic language. We also ask journalists and researchers to refrain from taking photos or recording audio without getting the permission of the entire room first.

For concrete suggestions on how you can help create a safe space, we very much like the Quiltbag++ Code of Conduct and The Recurse Center User Manual. And some open source project folks like The Contributor Covenant.


We try to announce our events in the following places (some are repeats of above):
