Send papers on behalf of others. I really don't know how this doctor learned, so let's say for the time being that you will hand out papers on his behalf. If it is not found out, if it is all secret, it will not affect his doctorate. Money is enough. The apparent author reached a compromise with the actual author. People don't need to talk to you about this, it really doesn't matter, but I'm afraid I used it in this paper, and then you have original problems. That will not only affect your doctorate, but also make it difficult to graduate. Because it involves not only plagiarism, but also cheating in doctoral graduation.
