We will perhaps have to agree to disagree, possibly based on some emotional harm you perceive yourself to have suffered. In the future, I might suggest maintaining a bit more emotional distance from someone you know only as a pseudononymous writer on a web site, and even then only for a short time.
@msgivings never claimed to be anything other than a writer. To this day, @msgivings, wherever, he, she, or possibly they, may be, is still a writer. Nothing has changed except that someone providing content that many valued (though it seems laced with some plagiarism, unfortunately) has been driven away.
As I said elsewhere, I consider that to be the real abuse, or possibly the worse abuse. Plagiarism is fixable with an edit and an apology. Hostility, negativity, and driving people away damages the platform and community at a much deeper level.
