Today I received the request feedback from a young and unknown colleague. I did a quick review of their work and I detected a little piece of information in the form of a prospective survey of a drinking water supply, as well similar works but with different bacterial targets in other papers. These works have been published in a predatory journal (https://predatoryjournals.com/journals/). Probably the sum of the different researches could be condensed in a unique paper that could be publishable in a minor but indexed journal.
Despite these facts, my question if we should collaborate in the dissemination of information contained in predatory journals.
