How can plagiarism be avioded.
Well first you should avoid copying a post letter for letter without adding your own personal knowledge and not also siting where you originally got it from.
*you can also avoid plagiarism by reading up an article, digesting it and the giving birth to a summary in your own understanding of the post. You can also state where you got it to be completely safe.
What you are talking about is rather copywriting, which is essentially the same plagiarism, since you use an invariant idea expressed by someone before you, and convey it in a different form, using another words. In order for the thoughts that you wrote in post to be really considered yours, it isn`t enough to read one source and retell it in your own words. You should familiarize yourself with several materials and form your view on a specific problem. And to express it in a form that will be understood by you first of all. Otherwise, you won`t be able to answer questions and complaints that will be put forward to your comment, you won`t be able to argue your point of view. You must really understand the topic so that you`re able to express the same idea in different forms, different expressions, without relying on the initial source.
