DonutHub

DonutHub is a moderation bot built around a single mass-ban action. When triggered, it attempts to ban every member currently in the server, rather than one user at a time. The request behind it was to make this available to everyone in the server, so any member could start it, not only staff. That is unusual for a moderation tool: most bots of this kind limit destructive actions to a staff role or a small set of trusted people, and Discord itself restricts banning to members who hold the Ban Members permission.

The permission question matters more than the feature itself. A bot can only ban people if its own role sits above those members and it has been granted the Ban Members permission. A member running the action also needs that permission for the command to work on their behalf, unless the bot performs the action with its own permissions. In practice, giving every member access to a mass ban means one mistake or one bad actor can empty a server, and bans are not easily reversed in bulk.

Server owners considering this bot should decide deliberately who can reach the command and check where the bot's role sits in the hierarchy. It suits servers that want a fast, server-wide removal tool held by a narrow group, not one handed to the whole membership.
