Not sure whether this anecdote fits the thread well, but does address &quot;don&#x27;t copy and paste from a website to, well, anywhere without examining what you just pasted&quot;:<p>I was administering a final exam to a programming class. Exam was done on class computers, so with me in the front of the room most of the time I couldn&#x27;t actually see what everyone was doing (and given the nature of the class, if you cheated it probably wouldn&#x27;t really help you anyway).<p>Grading one student&#x27;s submission, the wording of most of the &quot;essay&quot; questions seemed ... odd. Nothing objectively wrong, but everyone has their own writing style and his answers weren&#x27;t, well, his. Scrolling thru one particular answer there were some blank lines after the answer ... and then a URL. The URL contained much of the test question. Checking the unfamiliar site, it was a paid technical-question-answering service, base price for answers $30 and rising depending on depth, quality &amp; speed of answer. <i>Copying-and-pasting the purchased answers added the source URL to the selected text, proving malicious plagiarism on the final exam.</i> I figure he spent at least $300 to fail that exam and get one strike per the school&#x27;s &quot;three strikes and you&#x27;re out&quot; policy.
