A lot of us web content freelance writers have found our articles stolen on this site, including yours truly. Some people have found poetry they originally posted from other sites. A note to any amateur or up-and-coming songwriters, poets, professional and amateur fiction and non-fiction writers - if you've posted lyrics anywhere on the web, run your name through the SEARCH feature and see if your lyrics are on there.

If you own the copywright, then you have the right to complain and threaten legal action. Good luck.
