By any word or means, I didn't say it's a copy/paste process!!!
But it is plagiarism and as well copyright infringement!!!
Unfortunately and no matter how good your intentions were or might be (in which I don't doubt) it doesn't free you either excuse you from the taken action.
(If you don't know or didn't get familiar by now about the difference between those three infringing categories (copy/paste, plagiarism, and copyright infringement), I would strongly advise you to do so now, if nothing else to safely stay away from possible troubles that it might cause you otherwise!)

Never the less, I would highly appreciate, next time when you would like to translate some of my articles, to ask for my permission in advance!
I know some members announced and publicly granted translation rights for their articles to any Steemit member who is willing to do so, but I didn't do that for my articles! Therefore, I would also suggest you to take such possibility (of non-given translating permission) into consideration when you are translating the work of other members too, before translating and especially before publishing, and to carefully check their blogs or directly with them if such allowance already exists or not!
