It may or may not be. After all, I am also an author (and editor). This kind of thing is hard to say. Our editors sometimes go to other websites to dig people (but I don't do that). You can add his Q first to test whether he is a liar. It depends on your own judgment. I can help you make a simple judgment from his words. The signing requirements of each website are somewhat different. Judging from his words, is this website too casual? Generally, regular websites don't say what to write. It doesn't matter if you are cheated, even the name of the website has not been left. This is so fake. Obviously, it is either a liar or an irregular website. This is just a personal opinion. If you want to test, I suggest you wait until she comes back.
