I love that algorithm as well!
From the email service discussion thread, I gather that you watched/read about Apple’s WWDC '21 yesterday. Based on Apple’s new Focus feature presented yesterday, I think it would be great to have a version of the Focus feature with Pure concerning call filtering to make sure that situations like mine or @iota’s would happen (i.e., overly-enthusiastic filter blocking calls from people we need to hear from but aren’t in the contacts list). On my end, my call blocker recently blocked some technicians from multiple companies who needed to contact me for directions to come complete orders. Not a good look.
So, perhaps different Focuses (or “modes” or something to differentiate it from Apple’s IP) could help:
- Off — no filtering
- Work — superficial filtering, perhaps drawing on [YetAnotherCallBlocker]https://fossdroid.com/a/yet-another-call-blocker.html) for inspiration (open source Android call blocker [GitHub page is in the linked page] that crowdsources a phone number blacklist) and anonymous callers, but not numbers that are unknown to my contacts and not in the aforementioned blacklist (as they may be new clients, colleagues, etc.)
- Home — everything @l1ghthouse mentioned put together for minimal disturbance
