Using Signal groups for activism
2 months 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.
Is everyone in your Signal groups named something like "E" or "🥑"? Nicknames can help!

- Signal groups are used for organizing mutual aid and rapid response networks during ICE operations.
- The nicknames feature in Signal helps you identify contacts who use confusing or frequently changing names.
- To set a nickname, tap a contact's avatar, choose 'Nickname', and enter a custom name (end-to-end encrypted).
- When you mention a contact using @nickname, others see the original name, not your nickname.
- Using pseudonyms in Signal profiles is recommended due to risks of infiltrators or device searches.
- Group permission settings (e.g., open links, invites) can allow infiltrators to join and expose identities.
Signal Problems

- Signal saves sensitive information permanently in account databases, including phone numbers and group metadata.
- Deleting groups or chats only hides information; full deletion requires deleting all app data and re-registering without PIN.
- Signal uses SMS authentication, making accounts vulnerable to takeover through SIM swaps or SMS interception.
- ACIs (Account Identifiers) are tied to phone numbers and can be shared with governments upon request.
- Signal is centralized, runs on major tech servers, and can be censored or shut down by governments.
- Alternatives like Cwtch, Briar, and Delta Chat offer better metadata resistance and no phone number requirements, but have limitations.
- Recommendations for Signal users include using virtual numbers, GrapheneOS, encryption, and avoiding sensitive activities.
