Did BarbieGirl ever play you or any other thoughts about this special account?

her tendancy to just start games and never make a move.
booted in turn 1

Might have MD QM turned on and doesn't know how to disable it? Mutiplayer > Quickmatch > Invite me to multiday games
Or QM template they don't like and don't know how to disable it? Multiplayer > Quickmatch > Templates

Sounds like you just need to block Barbie and move on, and simply dont join any games with them if all they do is boot.
