Having seen plagiarism first hand, sometimes it exceedingly blatant. Like copying from a PDF that was produced via LaTeX — since LaTeX hyphenates words to split them across lines, if you end up keep-ing the hyphenation in, the te-xt reads like this.

I've seen way worse: a Word document submission that preserved the style and fonts of the sources the plagiarer stole from. As in, font "Calibri 14" only appeared in paragraphs nicked from a source entirely written in that font - and the adjoining paragraphs weren't even size 14!!!

Sadly, this idiot won an award before I was able to see their work, so they had the confusion of receiving an award, and THEN being told they were being spanked for unacceptable behavior. Since they were too stupid to hide the most blatant clues, they had a hard time comprehending this duality.
