Haha. Made me laugh. I expect he was blocked for a fairly inane reason. Maybe he expressed an opinion that someone didn't like, and they didn't want to see more of it. Or maybe he was just showing up so much on the recommended feed, that the reader got tired of it and blocked him. :)
I lost some followers when I criticised Greta Thunberg - you've got me wondering if they blocked me now!
I am currently blocked by someone who took offence when I was trying to help him by trying to explain to him how to overcome a problem he had with Medium's editing functions. I admit, I wrote a very short piece about how I was blocked for trying to help.
I did it because those stories earn a few more bob than most my others. And I was dumbfounded. But it was a 100 word story of no great significance, and I was more upset that he'd misunderstood my intentions so badly.
