MKWii: Match making optimizations

Here is video proof of this strange phenomena happening live:
twitch.tv/swordofseals/v/52825041?t=05h05m35s

Scenario:
Voting Screen
3 players left
2 players joining (1 player tried again after kick)

Problem:
Players can apparently join the room during the voting screen.
(This is similar to how Mario Kart 8 Day One DCs worked before Nintendo applied the server fix)

Symptoms:
Watch the voter count in the bottom right flicker as players enter and leave the voting screen.

Fixes:
Joining players are listed as "guests" on the Wiimmfi page.
Kicked 2 players while they were joining inside of the voting screen.
1 player tries re-entering the room while the voter count is stabilizing. Kicked 1 player again.
Room count is restored to a sane value. Game confirms that this is correct and proceeds as normal.

I've explained this before. If the room has the suspend bug, as soon as the player who caused it leaves, the game switches off the suspend flag regardless of where it is at the moment. Which of course makes bad things happen, the rooms do not advance in that state unless coincidentally nobody joins.

They are? I could've sworn they weren't, I've seen so many people rush rooms at once lately. Well, that works!

We all slip up

Are these settings still active? Or did they change?

At the moment, despite what the settings say, I don't think the features that prevent rooms from being joined too quickly work properly (hide and no-connect). It seems like any amount of people can join a room at once, unless a modification to the game (like CTGP) stops that from happening.

I remember originally when these features were announced and enabled, they were extremely good and immediately effective, but nowadays it's similar to how things were before they were implemented. Any idea why that might be?

Oh, could it happen because everyone is joining via friends list rather than by searching?
