I was infuriated recently having put a section on my site about 2007 hairstyles and then submitting same article to an article site, that the article site ended up outranking my site for the term and has got 100000s page views of my article. I still get traffic on the term, but keep going from page 2 to 3 and out the rankings altogether on it, whilst ezinearticles remains steadily at number 8 on page 1!!!!!
