Well, not accidentally see a nice site. Site for knowing who had plagiarized articles in our blog. The way is easy, do not need to register, just put the address / URL blogging then click the button "GO",
Just wait a while then straight out who is taking or copy and paste your blog article. If to know who plagiarized a particular article or post that you put it there is a link of your post title, so who will be caught plagiarizing that your posts.
But unfortunately for the free version we can only know a few wrote, so it can not know all that copy and paste our blog. But quite right for a little peek. Ok .. for those who want to know the address just visit >>> http://www.copyscape.com
