What would happen if some paper is published in a main journal and the main idea is extracted from some other paper originally and previously published only online or on some secondary source.
What will happen if there is no reference to the original paper?
What the authors of the original paper can do to prove the original authorship and plagiarism?
What if the original paper is a preprint published only on Research gate? ( I understand there is no prove on the date of publishing on RSG)
