I carefully examined life360.com, trying to put myself in the shoes of somebody who was stalked, magically divined that life360 was involved, and wanted to report the issue. The extent of my options on life360.com are:
1. Do Not Sell or Share My Personal Information
And that's it. There does not exist a "contact us" or other general mechanism, and there certainly does not exist an abuse reporting mechanism. If that happens to exist behind other filters or paywalls then it's not relevant when discussing how the average customer would interact with your website.
With that in mind, I would expect an exactly 0% abuse rate regardless of how abusive your product actually is. You confirm that number. I'm not surprised.
The ball is in your court. How do you prove to the world that you _actually_ care about abuse? How _should_ a real abusee interact with your website? Why isn't it obvious? What are the exact numbers? And so on...
