Keeping group chats as secure as possible

When setting up the group chat make sure you follow these rules to keep it as secure as possible

  1. Ideally only add people that you know well or are verified by others (trusted rebels)
  2. Make sure only admins can add new members to the chat.
  3. If you are doing spicy actions make sure people use pseudonyms and burner phones if possible, and that those are added to the correct chats (with their normal names and numbers removed).
  4. Make sure there are separate secure chats for action days or spicy actions so that you can delete them afterwards.
  5. Make sure you set disappearing messages. If actions are happening soon, make sure you set disappearing messages to a day or a week. Otherwise 4 weeks should be fine (Only Signal can do this automatically however Admins in Mattermost, WhatsApp and Telegram can delete others' messages.)
  6. Make sure you keep the group links off.
  7. Remember that many chat platforms attach media and files and links separately, so admins should regularly check that old media files and links are deleted
  8. After the chat is done, and everyone has agreed that the group chat is done with, leave the group and delete the chat off your phone
  9. Some members may not do this, so once the chat is done with, admins can remove members individually and then delete the chat off phones by deleting the group chat altogether - in this way people are not on lots of different chats that have ended which may cause security issues should someone’s phone be seized.
