That's the thing, they don't review their apps, and they actively ignore people flagging apps that are scams or otherwise malicious. Much like their ad empire, its all bots and people making money for pretending to care.
Even worse, they DO review their apps. And they make huge hassles for anyone to submit apps, including forcing you to create a new account if your tiny side project with 0 permissions didn't fill out a form in time (grumble grumble).
It is false to say they are great at it. It's also false to say they don't review it. They remove some, but they're not great at it.
