Very off topic, but on the IT-literacy angle. I wrote a website for a group of shanty singers I am with, which launched around three weeks ago. One of the things it can do is email a setlist to everyone taking part in gigs.

Roughly half of the recipient's systems put it in the spam folder. The other half are quite happy. I have sent it to a spam-assessment site and it is 100% clean/not spam in its opinion. My ISP asserts all the Internet configuration is correct.

It gets to me fine, which is a shame because otherwise I could investigate. I don;t have access to their machines to try to find out why they think it is spam.

Moral and relevance of the tale: IT systems are tricksy and just because things work for you does not mean it works for anyone else.

Oh, and for me, the articles being discussed are behind a paywall.
