Hi Chuck,

You're talking about 50+ database operators half of which don't
identify their principals and offer no way contact staff or interact
with them except, sometimes, through narrowly defined reporting tools.

Google is a prime example of the problem. They write great algorithms
but their confidence in those algorithms far exceeds their greatness.
The current catastrophic mess with Recaptcha should offer a cautionary
tale for all.

You would think so, but I have a friend who is visited by police every
few months because the prior owner of his house is a petty criminal
still committing crimes and their database shows the house as his last
known residence.
