Has Shadow Banning Come To Substack?

My last couple of posts I noticed a lack of engagement, not that us amoebas get much even on a good day. Since they were about COVID I was planning to write it off as COVID Fatigue.

But I decided to do a test with an email account I set up with substack early on to Test if it was working correctly (receipt and engagement). So I checked to see if my emails were sent out and received. Check. Then I liked one of them, and it showed I had liked the post. Check.

I then went back to my substack and it did not show an increase in likes.

I checked my active substack email and notifications to see if notification of my like was received. It was not. But two others were.

Could it be a glitch? Maybe. I will watch for this by trying again tomorrow.

If I am shadow banned, for what reason? After all, this is the land of almost anything goes, or is it?
