Losing games without joining

[Szei]

I was looking at OSN recently and noticed that I apparently lost 2 games in the last 24 hours on an account I haven't logged into for over 3 months (and no devices are logged into that account). They are 2v2 games and I'm wondering if it counts as a loss if you never accept or decline an invite to a 2v2 game and the time expires.

I'm player 2 in both games and the games ends after player 1 takes his/her turn since I never joined in the first place and therefore didn't make any moves.

Just wanted to make sure it's just a case of autoforfeit when being invited by someone and not declining or if I need to be concerned that my account has been compromised.
