Valve did the right thing.
You can’t filter all abusive (note not bad games) with $100 or $500 or even $1000. You’ll just filter some.
But with that fee, you risk to block some potentially awesome ideas/games.
Steam just needs better targeting system, and they’re aiming for that, right now!
If you know how to make/sell your game. Then $100 or $10000k won’t be a factor.
