Blogger Darren Rowse calls out another blogger he says is using content without crediting the source:

Have a look at Blogger Tips (no follow tag used) - a blog that is filled with either posts that are ‘free articles’ or other people’s content. In both types of posts there is no credit given to the original author.

I’ve got nothing against using free articles (I don’t think its the smartest way to build a blog) - but this blog isn’t even crediting them. Free articles are able to be freely posted on your blog - but you’re obligated to include a signature with a link to the author.

Content stealing is probably more common than people realize.
