Thank you for that.
I think it goes back to how we look at the digital ecosystem. I don't know if any of you answer phone calls anymore from phone numbers that you don't recognize. There's a whole generation of people who no longer pick up the phone, because trust was broken. Our incentive here, then, is to preserve trust in the digital ecosystem. That's how we look at it. That's why we've built our business model and our enforcement mechanisms so that we are not making profit from this. We are able to block these ads before they're ever seen by users, so that they don't enter our ecosystem.
We try to make it as unattractive as possible for scammers to even come to Google in the first place, and they'll go look elsewhere.
