In turnitin’s defence, in my recollection their training material explicitly and repeatedly tells you not to do this - that a positive turnitin result is not the same as plagiarism, and that all positives should be manually reviewed. The student-facing side of it can be bad, as it errs on the side of extreme caution. When I (as a TA) had to mark dozens and dozens of papers pre-screening for obviously copied paragraphs was a very nice time saver. Otherwise the only students I would catch are the ones with poor English skills (grammar switching from flawless to flawed and back again is a pretty good tell that the paragraph was written by somebody else).
