Plagiarism can be considered a violation of academic integrity and journalistic ethics. It can be punished, you could get suspended, even expelled from school, or work, you could pay hefty fines, and even risk imprisonment.
Plagiarism may not be the same in all countries. Some countries, such as India and Poland, regard plagiarism as a crime, and there have been cases of people being imprisoned for plagiarism.  In other cases, plagiarism may be the exact opposite of  “academic dishonesty”; in fact, in some countries, plagiarism of professional works is regarded as flattery.
Generally speaking, plagiarism itself does not constitute a crime, but just like fake fraud, it can be punished by the court for prejudice caused by copyright infringement, or infringement of moral rights.
Plagiarism and copyright infringement overlap to a considerable extent, but they are not equivalent concepts.  Many types of plagiarism do not constitute copyright infringement, which is defined by copyright law and can be determined by the court.
