I told my sons about plagiarizing in my college class last semester. My eldest son said the students were foolish.
“First off, you should plagiarize from books. That way you won’t get caught from the net.”
“Then, if you’d just move the words around in the sentence, so that they’re not in the same order, you won’t get caught either.”
(Quotes probably not exact. My memory is holey right now.)
Won’t always work. There are tons of book quotes floating around the web. I’ve caught plagiarism from a book using the web.
Moving sentences around doesn’t work, either. When I suspect plagiarism, I always begin with a fairly small snippet, no more than a sentence.
