But it can get complicated. Just pasting part of a work could be looked at as a review. Also, it would only be against the Law if the person re-writing or pasting an Article was doing it for money! As an example, if you got up in a Bar and sang a popular song, you would not be in breach of Copyright.
But I was a professional singer; and for every song I sang on-stage I had to pay a fee to The Performing Rights Society. Unless the composer had died 70 years before!
It is not all as simple as it seems. I think you are "looking" for breaches of Copyright.
