@tesselart, welcome to the world of phishing. There is a Steem user @harley1989, but they did not repost my article. The scammer did not copy all of steem.it, but likely a very small portion (just the page with my post). The scammer hoped I'd login on the fake steem.it to downvote the plagiarizing post. However, I wouldn't really be logging in, but instead forfeiting my private key to the scammer. The steemik site is an impostor meant to trick users into disclosing their password to the scammer.

As an aside, this is why you should use a password manager, which remembers domain names, so you know something is up if the site is not the same domain that your password manager has stored.
