If you are rarely removed from a game in progress and choose to not remove yourself then this will not occur. As stated above, people have differing and personal experiences, particularly with lag (which means the extent of, and the tolerance of).
I would imagine freezes and disconnects alone will not cause probabtion, but if you are unsatisfied by the game's functionality but try to play on, however, you will be punished further (as Chesty cited) when you attempt to moderate and tame your gaming experience by being suspended (temporarily) rather than compensated for your troubles.
Again, a functioning experience for someone and this system may work, that's hardly the case for everyone though.
Furthermore, does BOII benefit from such a system, here and now. I would like to know how.
Good post, I don't condone quiting but if the game isn't going to function properly then I can't blame people for quitting. I'm suprised I didn't get probation today, lots of quiting due to horrendous lag. After downloading 1.06 I couldn't find a game where I wasn't constantly getting shot around walls, my gun was shooting marshmellows and I was getting insta deathed.
