I don't know what happened, but this got INTENSELY worse for me in the last ~6 months. I never respond to them and mark as spam and move on, but I get multiple calls and texts from unknown numbers every day. Sometimes it's the "hey, I'm sorry to hear about that thing that happened to you" kind of bait, but lately a vast majority of them are trying to offer me business funds or loans or whatever.

I have no idea if my number made its way onto new lists or if the problem just got worse in general, but it's making my phone borderline unusable. I miss any calls from legitimate unknown numbers because of it (delivery people, etc). I've also had my phone number for > 20 years at this point and I can't stand the thought of changing it.
