Plagiarism sometimes creates legal and ethical problems for students and faculty. It can have serious consequences. Fortunately, there are ways to stop plagiarism. There are many tools available to detect plagiarism, e.g. using software for detecting submitted articles. Also, there are many ways to punish a plagiarist, e.g. banning plagiarists from submitting future articles for publication. In addition, scholarly journals should clearly state their policies regarding plagiarism and require authors to sign a statement indicating that their articles meet the requirements of original work. The reviewers should be supported by the journal's board and editors when they report any occurrences of plagiarism.
