Two weeks on the internet these days can be the difference between success and complete failure of a product or service. Imagine you prepared a campain for something available only from your site for a couple of months... you've got ads, articles, etc. with the release date. Some competitor files a DMCA takedown notice that day and anyone who heard about your product gets a "404 account suspended" response. It doesn't cost them anything and you don't matter anymore - in two weeks people won't remember your product.

Now I wonder how hard would it be to file DMCAs for the government websites... white house, etc.
