According to plagiarism.org, "The Josephson Institute Center for Youth Ethics surveyed 43,000 high school students in public and private schools."
The study was further tested and found that, "59% of high school students admitted cheating on a test during the last year. 34% self-reported doing it more than two times. One out of three high school students admitted that they used the Internet to plagiarize an assignment."
It's easy to see that those men were cheating with almost no problem. Even if the video was sort of a joke, this can be done on tests easily.
It's insane what kind of technology people will use to cheat on tests instead of just studying for tests.
