Moderate multi accounts

At this moment, discord allow and help with using multiple accounts. This is really good feature, however, it can be used as a boost to abusing. There is no truly help for moderation servers.

I mean - if I moderate server I wanna see how many real user I have + I need help to detect toxic and already banned people.

So my proposal - Server admins should see all multiaccounts on the server and in banned section. Something like that:
User A => check profile = User A, User A.1 (on server), User A.2 (banned)
