I’ve actually needed something like this, but not for everyone. I want to be able to automatically add a Discord role to anyone that is a follower (or at least has a connected Twitch account) to a member role so that they can get to the whole server as quickly as possible. Those who aren’t a follower or don’t have a connected Twitch account are instead given a guest role which can only view a special #guest-room that’s accessible only to guests where they then await a mod to manually verify that they’re not a bot. The reason for this is that this keeps guests from seeing the names of members on the server and thus keeps the vast majority of bots from DM’ing people.
As it is right now, I just have it so everyone has to go through the guest room first which is inconvenient for lots of folk, especially if a mod isn’t online at the time. It’d be very handy if this feature was added as a way to authenticate new users and keep the user list out of the sight of shitty bots.
