My site is in a similar slide: I published RSS feeds, (With same title and starting sentences) We also Use syndicated content sometimes when we feel its quality and helpful to our readers. (Seat belt articles, baby seats) So now I think it looks like my site is spammy or worse yet a copy cat. What is also weird i found a site with three articles that have links back to the same page the article is on, yet they rank higher. Yet we are fine in bing and yahoo..
I once had a criminal justice professor and she said she would rather have 9 criminals free then 1 Innocent person in jail. Guess google doesn't have same theory lol.
