I'd love to know what people who set their phone to auto ignore anyone not on their contacts are missing. Just last week I had two random calls from new to me numbers that were actually calls I wanted to take.

Spam calls are annoying but only take a second to figure out what they are and I can choose whether I want to engage and waste their time or save my own by just hanging up. Though I don't get many lately, not sure if it's Canada improving its phone system or my own phone's filtering (I've seen people mention pixels do well filtering but I'm on graphene so no idea if that applies to me).
