I checked all my games since I'm back, and made a pizza chart with results:
"Open" slice represent the games with open seats that I joined, most of these were 1vs1 auto-games. It include all ladder and tournament games as well. ~60% of my games.
Games included in "Me" slice are those I created and invited someone (no open seats), "also me" are the games I created with open seats. ~34% of my games.
"Others" are the games where someone invited me to a game. ~6% of my games.
Conclusion: People don't like me :(
