<p>When one suspects plagiarism ie a prof, they will look for the evidence and then confront the student. They don’t warn them. The likelihood someone and the school is following this thread is nil. </p>
<p>As for making a portfolio with copies of others art representing it as their own, not so farfetched. I have a friend who posts amazing pictures of animals she has painted on her Facebook, the likelihood that an admissions person would suspect it was "stolen"work would be very unlikely. Not that my friend steals the work, but that someone could steal hers and claim its their own. Same with photography, sculptures, etc.</p>
