Not very wise of you to depend on Discord and Google Sheets instead of more open alternatives when you're organizing a group whose purpose is to literally preserve the victims of corporate censorship.
Discord is used for the simple reason that the current goal is to gain as much traction and participation as possible. The Rocketchat server I host, and the IRC channels I could have used would both acted as barriers of entry to a lot of possible participants.
Perhaps with time I can push for a migration to a solution I host. For the moment I'll stick with these tools, and plan for their failure as best I can.
