Коллега переслал мне нижеследующее сообщение полученное, по его словам, от индуса:
Dear Professor/Doctor,
I hope this message finds you in good health and spirits!
I have many papers that need to be cited.
If you cite my paper, I can give you a thank-you fee per paper.
My articles come from different authors, and there are dozens of articles in the same research direction, so you can quote more than a dozen of my articles in one article.
