Using Signal groups for activism
2 days ago
- Signal is secure for activism due to end-to-end encryption, no access to metadata or group info, and phone number privacy by default.
- QR codes can be used to quickly turn in-person meetings into private Signal groups with disappearing messages and admin approval.
- Semi-public Signal groups can be managed with vetting (e.g., requiring existing members to vouch for new members) while maintaining privacy.
- Announcement-only groups, where only admins can send messages, are ideal for rapid response networks like ICE raid alerts.
- Signal is user-friendly, free, and open source, making it accessible for diverse movements without a steep learning curve.
- Permissions and group links allow flexible control over membership and messaging, enabling safe large-scale organizing.
