If an article been copied and change it into other language? Is that still under copyright? can i sue him? But most of article been copy here and there, article post to blog and to forum.
If it is your work, then you have rights to the article. Can you prove it is your article? Are you willing to put up $1000's in potential court costs? You may end up putting $1000's into the legal system just to settle for almost nothing, and what if the other party that you are going after, what if they have nothing, then what? You got it - you get nothing, and you are still out. I ran across one article saying that this company is going around and buying up copyright stuff, then turning around and suing every site that has the copyright that he just bought...He seems to be doing quite well, and he also has a lot of money.
If someone able to prove that is his article, i think next time you will see less people writing about seo in blog because SEO article mostly the same even they have more than 100 ways method of seo but only few way to share it out. New content the article can share only will be different story and different problem face and using SEO only. If he able to gain copyright, he will be rich until there are other people find a new method to cover this SEO methods
If you got copyright you only can sue , if not you cant do anything with it. Every country have different copyright, if like china, their copyright are not that tight as other. That why they cannot control their country pirated and copyright. They can simply take mcdonald name and open a MCD with a slightly different name or different logo and sell the same thing in market. This is legal for them !!!
