A very good debate that is generated with the points very well explained by the friend Juan, I think that the reesteem is what is well seen in case any of us likes another publication.

In the case of cross-publishing, I think that it should be complemented until a better end is achieved, that is, it should not be seen as plagiarism. I am not an expert on the subject, but I think that if the person who liked the content of another user, he or she could generate a publication with the link, but some premises should be set so that the generated publication is not plagiarism, For example, suppose I want to cross-publish this article, I could generate a cross-publication that would include an explanation of what I understood of the publication and an analysis of why I chose it among my favorites, I think it would look less banal, until at least a solution is found to the issue that only one hive is allowed to be used as a label.
