So now you can get permabanned for being afk?

If you serially do it? Probably.

oh? if that is the case it's news to me.

Got a source on that?

The problem would have to be very severe over a long period of time.

Well, rather late than never.

Er... why wouldn't you be? You're serially ruining the experience for at least 4 players at a time.

See here.

"While we hope it doesn’t ever happen, but if a player fails to stop AFKing or leaving while in lower-priority matchmaking, continued offenses will result in permanent bans."
