By default, admins and moderators can assign roles manually through Discord's server settings panel, which can quickly become annoying if you run a large server. The most common workaround is using a bot to enable "reaction roles," which automatically assigns roles when members react to a message with a specific emoji. One way discord roles automation differs from other team chat apps is how it uses roles. Rather than a traditional community role structure—admins manage the server, moderators manage the conversations, and members can only post—Discord's roles are infinitely customizable.
