As I said, you want Medium to police user interactions. You want them to investigate the conversations we are having with each other and take sides instead of just responding to complaints.
This is a plea for authoritarian type control on a speech platform. I applaud Medium for trying to have a content blind approach.
As an example, I have been blocked by other users after they’ve littered my posts with graffiti in the form of antagonistic, argumentative comments. My philosophy requires me to counter those public statements instead of allowing them to stand uncontested.
To recap, you commented on Edwin’s piece. That’s his writing, his article. He replied to you. You didn’t like what he had to say in public, so you sent him private messages after you googled him. Now you’ve written a whole piece, and seem committed to the idea that you were harassed by him replying to you on a piece he wrote. But you were chasing him. You were commenting on his piece. There is no requirement that he suffer fools. It would be nice if we were all polite and respectful to each other, but your first step was leaving a belittling and childish comment where you admitted you didn’t even finish his article.
You were not respectful. You continued to leave comments that you knew were pissing him off. Then you googled him and sent him a note.
You even claim you didn’t dox him, but you admit you did here: you tried to figure out who he really was. That is exactly what doxxing is:
search for and publish private or identifying information about (a particular individual) on the Internet, typically with malicious intent.
I’m going to make this as simple as I can: he cannot harass you by continuing to reply to comments on his page. It’s your choice to keep going there. That’s why Medium identified you as the harasser: you were chasing him. He didn’t send you any notes, did he?
That is the limit of their investigation.
