When I don't recognize a number, I don't pick up. I tell them to email me/text me and that they provide when they called and with what number. Then I might call them back.

Asking extra effort from unknown people will do a few things:

- Scammers won't do it (not yet anyway)

- Spammers won't do it either

- Anyone lazy won't do it
