It is a shock to see that some of the researchers are including others' articles in their profiles, by taking advantage of the similarity of names to increase the RG Scores.
No, not like that. If any one enter the Non-authorship papers, then the Researchgate won't accept it as his/her publication. So, it isn't increase the RG score. Nowadays, in research we can use the plagiarism software to find "How much similarity is there with the other article which was already published in the other journals".
That why, in some journals they are using the plagiarism software before publishing the particular paper in their journals.
