The influence of paper fraud on the second author mainly depends on the contribution and responsibility of the second author in the paper. If the second author only participated in part of the research work and did not participate in the writing or revision of the paper, then he may not have much influence on the overall quality and authenticity of the paper. However, if the second author makes a great contribution to the paper, or bears a great responsibility for the writing and revision of the paper, then he may be implicated to some extent because of the falsification of the paper.
