Well if you are silently placed on a hide list (by manual human intervention without you being able to know without a third party), then by all means that is a shadow ban.

Regardless of whether you were notified, if you can see that you are banned, it is by definition not a shadow ban.
Shadow ban is explicity "pretend to user they are not banned, but don't show it to everyone else"
Like say getting shadow banned on reddit or HN, you will see your stuff when you're logged in, but anonymous or other people wont.
Search equivalent would be you getting your own site when you're searching but nobody else does
If you use Bing webmaster tools (a logged-in account for the use of the domain owner/content creator) and you can see indications that Bing indexed the content and no indications that errors preventing it from being eligible to show then it is certainly at least closer to a shadow ban than I originally thought.
Still, any reference to a "feed" entirely misses the point unless Bing is the one also serving that feed. I can't see any evidence that Bing displays a feed to the poster.
