Oauth2 Scope : Add member to a server once

[leElvyn]

Why is this needed ?

The guilds.join Oauth2 scope can be very useful. It allows you to add a user to a guild, with the roles you need.

This can be very useful in a lot of situations, but two notable ones are :

• Joining a guild that requires linking your discord account. Using the code grant allows you to add the user to the guild, bypassing verification and giving the user the right roles.
• Joining a private guild. The web server can check a database or any other authentication source, and you don't have to bother with verification, invites and making sure nothing leaks.

Unfortunately, a lot of apps make abuse of that permission, and will attempt to add you to "partner" guilds, or other if you don't immediately unlink the app, and thus a lot of users are reluctant to accepting prompts containing the guilds.join scope. Having this scope prevents abuses.

Alternatives considered

You can simply accept the full scope, and instantly unlink the app. But that can cause issues since it can unlink the account to the app.

Additional details

This guilds.join_once would function exactly the same as the current scope, but it expire after only one successful use.

If the point is to reduce abuse, that would imply asking abusers to use this more limited scope rather than the more permissive one, which they would likely not do. Unless you're asking to fully replace the current scope with this one, I'm not sure this is really useful
