There is no strategy in purposly losing, and you shouldnt have to scan every running game every day to see if someone is moving 0 in everygame jus to quit. I a sure this wont become a big problem, as most people who do not want to play will not enter and create as many games as he has done.
I see it more like unfair inside information when only one or two people in a game know of someones intention to bid 0.
What would be so hard to just come on here and say, I am out on all my games... no unfair advantage for anyone.
