The WordPress Team

Here's the story. 

For some years, we managed the web presence and other techy stuff for an author, Jefferson Galt. Some years into the relationship, our excellent server provider was sold to a bunch of cowboys who made a pig's ear of transferring so many of our websites we almost ended up in litigation. We moved again, despite the shabby attempts to prevent us moving, to our current provider, the excellent Siteground. 

Galt said he was feeling a bit guilty at the work we were doing and said he'd heard that Wordpress was designed for people like him who are utterly clueless. We told him not to, that we'd spend more time sorting out stuff that didn't work than we'd spend doing it right ourselves but he was adamant. So we installed it. It took him less than a week to decide he hated it and couldn't work it. 

So we scrapped Wordpress and build a new site.

A couple of years later, he decided to retire (his books are still available) and to shut the website. 

And his domain name expired. 

So here's where it's weird: 

How does a dead website send emails saying that software that isn't present has been updated?

We don't know. But we do know that something's off. Whatever it is, we aren't engaging because nothing good will happen and something bad might.
