Good articles are not afraid of plagiarism; Fraud, I think you have the ability to distinguish right from wrong; If you can't make good friends, you can only say that you are shallow in judging people; If you are still worried, don't use the internet to get detailed comments, because even in professional forums, there will definitely be some people with ulterior motives. In your life, you can find several mentors or confidants to talk about your articles. If you say that you have no confidant and mentor in your life, you should first care about your social relations. After all, people are social people sooner or later. Weibo can consider it, provided that you give up all worries and study with a sincere heart. But judging from your fear of plagiarism, you have a lot, and it seems difficult to let go.
I suggest you find some friends in your life to read your article and listen to their comments, then post the article online and listen to the comments of netizens, and then compare the two to know which is right (you must put down all concerns when posting articles online, otherwise don't post them at all).
