I received an email from the Bing Webmaster Team:

We hope this message finds you well! We've noticed it's been a while since you last visited Bing Webmaster Tools, and we've genuinely missed having you around!
Webmaster Tools has undergone some exciting updates and improvements recently, and we think you'll be pleased with the enhancements we've made. Your feedback has always been valuable to us, and we're eager to hear your thoughts on the latest features.

My main project, The New Leaf Journal, was blacklisted by Bing in January 2023 and not reinstated until July (I received formal confirmation near the end of August). The process was annoying enough to prompt me to create a GitHub repository (my choice of Microsoft-owned GitHub was intentional) collecting Bing-ban stories. I still do not know why Bing took adverse action against my site (they will never say), but I can report that our standing with Bing and Bing-dependent DuckDuckGo has finally returned to what it was on the eve of the troubles in January. Of course, this Bing email is a misunderstanding for a reason unrelated to my complicated Bing history. I usually use a Google account I set up for Search Console purposes to log into Bing Webmaster. This email was sent to my Bing-only account that has never been used. Bing can rest assured that I am alive and have seen its new Webmaster features.
