I'm not sure how long this has been going on, but Blogger has been dumping ALL comments into the Spam Folder. I just noticed this a few minutes ago. Some are definitely spam, but most are legit comments that should have given me email notifications. They weren't.
I'll dig through more tomorrow and will look deeper to see if any settings were changed inadvertently.
I apologize to all.
I suspect it will be a busy day tomorrow...
Edit: Somehow the email address for moderations requests was set to: nothing
My regular email addy was deleted, so no notifications went out. Likely happened during a recent blogger update. Sigh
