Using one of my article

I recently came upon a website and to my surprise they had an article on the site that I authored. The website did not include a back link to my website, so I guess that leaves everyone visiting this site the idea they they authored this article. The article is titled The Perfect Catch - A fishing knife.. I wrote this article and it was accepted by ezine.com and that is where it can be viewed. Is this how it works? Anyone can just go to ezine and copy and paste any article, put it on their website and take credit for it. This stinks. All the hard work I put into writing my articles I don;t appreciate this. Is there anything I can do about this? If not then my article writing days may be over. I'll just go to ezine.com and copy and paste any article I think useful and take credit for it. Can anyone tell me if there is anything I can do about this. Thanks...James
