Too many timeouts means you left other players, who really wanted to play an entire game, hanging on numerous occasions. The rest of us do NOT want you until you can demonstrate greater responsibility and consideration.
If you can't keep track of your game because you have too many games, etc. then don't sign up for more games than you can handle. I've had tricky positions at times when life's responsibilities kept me away from the board for a couple days, but when I had several minutes (after spending many some previous time considering the position), I took the time to make the move rather than take the chance I'd fall asleep, spend more time at an appointment than I expected, etc.
Then if you want to prevent timeouts it might be a good idea to turn it back on.
