I have the most popular blog in a certain niche, and there are only a handful of competitors. Not long ago, I started adding my posts to a blogging platform and having my posts redirect back to my site when they were clicked. Another member of the blogging platform noticed that it was an original he had made. I know that wasn't right, so I told my co-blogger no more posts are to be sourced, no matter how good they are. So we removed our 10 copyrighted posts out of 350 from our main blog. But the guy was still not satisfied. He reblogged our blog post of his original, and added something about not appreciating what we were doing. However, as a result, we have received a pleasant surge in traffic from what he did. Our adsense income has doubled.
