Copyright Laws

I recently read an article about copyright laws. It stated that many dictionaries and encyclopedias put in fake words here and there in order to protect themselves against people stealing their content and publishing it as their own. For example the word "esquivalience" is a word placed in the New Oxford American Dictionary. It's not a real word and they are the ones who made it up. So if that word ever appears in another dictionary or online source, they can sue for copyright infringement. I'm sure that's not the only fake entry -- so if you're ever tempted to play around with content from other sources that is copyrighted -- don't do it, besides being illegal, the consequences of getting caught can be quite severe.
