> I honestly wish I could deny-all by default. Hey email solved this problem for me for email and I want an equivalent type of service for phone and text, now.
I would love an information-lock based system. Basically those "What's your mother's maiden name?" security questions, but repurpose them so other people have to answer them before they contact me.
I'm pretty sure even a basic "What is my name?" security question would eliminate most spam. For those more infuriated by spam, you could set it to something random and effectively have a password to contact you.
