I have been trying to research all of the copyright laws and it get's really fuzzy. Infringement laws, fair use laws, and safe harbor laws all apply. Today I came across another copyright with the added text and noticed at the bottom of the screen the word share. Seems contradictory to me. I placed this in the hands of someone that can give us a definite answer until then I think we are safe to proceed as usual until we get a definite answer since from what I read we would have to be warned and given a chance to take down the article.
