I don't understand @spamminator always comes to my posts and downvotes my posts. is there a clear reason? there is also no notification, is my post plagiarism? but i don't plagiarize. what happened? is it because my account is from the old steemit?

and because @spamminator came to my post as a result I was also visited by several other downvotes, @gniksivart @freebornsociety @buildawhale
