Sorry, but I really don't understand what you mean by this.

I just found out I was blocked on Medium by someone who's writing I really enjoyed—though I often disagreed, privately, with her positions. I had responded to one of her articles, in a positive way, & she responded back. It was all pleasant. I just thought she hadn't written anything lately. Suddenly, however, I find myself blocked. No idea why.

Not sure I'm being taught anything here if I don't know the why of it.
