For me it started at the beginning of 2021. I still get the most obvious kind of spam. From Bitcoin to Paypal to USPS. About 100 messages a week. Before, I used to delete them, but they just kept coming, so I decided to let them sit there. At one point I had more than 1000, when before 2021 I had less than 10. Now I'm down to about 430. I think the system deletes spam after 30 days. So at least that thing works.
