He asked what service to use. You said, "I sue this one." That's implicitly answering his question and recommending the use of that particular service. If that's not what you intended, why did you choose this particular place and time to tell everyone what plagiarism scanner you use?
Wrong interpretation. And why are you the only person concerned with the kind of plagiarism detector that I use? I have not specifically told him/her to use it. It seems you did not go to see a doctor as I recommend yesterday. That asshole disorder is really driving you crazy.
