Hey Noah! This is pretty sweet. Would love to send you a t-shirt. Care to drop me an email at [email protected]?

Sure thanks!

Are you aware of any robocallers that have answered your "simple arithmetic question" correctly?

Not that have targeted me!

If you have encountered any robo callers who have please let me know.

My idea was that if the robo callers get past the simple arithmetic questions I would give them harder ones like "which of these items doesn't belong? 1) ball 2) blue 3) red 4) green?" or other SAT / standardized test questions.

Which of the following is my name? a) Rupert, b) Noah c) Robert ') drop table us_phone_numbers;

Ditto, except the one I wrote only works for landlines. https://github.com/dgnorton/norobo

Cool! Definitely very helpful. I still get tons of robo calls on the landline.

That is very cool. I love how retrofuturistic it feels.

Very neat! Given that an average user doesn't receive many calls a day, it would be cheaper to operate if this could be implemented completely serverless using Cloud Firestore & Cloud Functions.
