Users with Discord connections are getting Discord API numbers (0 by default now) appended with an `_` to their 7TV `username`s

This wasn't voluntary, their names were automatically changed, not on connection link, but all at once

Some examples, using the following query

{user(id:$UserID){connections{id platform username}username}}

Works as intended. Usernames are updated to reflect the user's first connection, at this time non-Twitch connections have extra numbers appended to avoid collision; this is a temporary measure until the phasing out of on-platform usernames altogether.

I'm trying to say that wasn't all their first connections, maybe they disconnected their connection at some point, and then reconnected, which caused a change in order, but initially a lot of their accounts were Twitch created afaik, as they previously didn't have Discord names.
This had some unintended effects for people.
