Hi,
following "problem":

1) you join an empty auto-game lobby
2) a player on your blacklist joins the game
3) you break your keyboard bc u have to waste your time with the idiots on your blacklist.

solution #1: dont join any empty auto-game.
solution #2: add a check before the game starts -> if opponent is on BL -> leave game.

It would be nice to see that in team games.
Auto games? You're blocking a seat for someone else.

Potential for abuse is high.

I put all strong players on BL and join an auto game. Easy money. Either the strongs cannot join or I get an opt-out.

I think it is the same reasoning that BL players may be assigned to you in QM and other games...

^ There is no way to abuse it, doesnt affect ladder or QM rating. BLed players can't join games you can create. Makes sense for 1v1 auto games to prevent players you have BLed from joining.

What if I blacklist everyone and take the auto game hostage?

There are Auto Games with coin ante -> BL is a great opportunity to abuse them.

Then don't apply it to coin games.
