I took a company to Federal Court for online copyright infringement many years ago. And it was in court for several years. I wouldn't want to have to do it again.
The main trouble I see with filing DMCA complaints (and I've filed many) is that there's no penalty for reoffending, and reoffend they do. Plus, many of the article farms syndicate the stolen pages, so the takedown notice you file with them doesn't affect the hundreds or thousands of copies that have been distributed. As you whack the onesthat show up in search, the ones that Google currently ignores as being "similar" raise their ugly heads.
Unless governments around the world put some teeth into online infringement laws, the only solution rests with the search engines. Google used to do a pretty good job with it, they threw that out the window on February 23. Bing still does a decent job.
