I wonder why Hasbro has been giving out so many CD orders while in the past they've never bothered.
i would assume that it probably costs them a decent coin to go out and search for every single thing that violates their copyrights, so they likely direct their attention to content that relates too closely their stuff (JanAnimations, for example, extremely close to the actual show), content that is sold for money (WhiteDoves plushies), and content that perhaps is considered "bad publicity" to them.
JanAnimations and Fighting is Magic are good examples of content that is just
too good. even with the disclaimers saying Hasbro was not involved with it, liability-wise they are professional grade creations that Hasbro can't let loose without possible repercussions related to their IP/copyright/whatever law.
some have actually been fake, or were never actually given such orders (i recently heard the stuff related to the Princess Molestia tumblr-thing was not actually because of Hasbro). i think as far as real Hasbro goes, they haven't really given out too many of these complaints, the ones they have are on projects that just closely resemble their property or were milking cash off their property and that number is pretty low.
they haven't gone after simple fan artists who just draw ponies. they haven't gone after simple remixers who actually warped the songs. in reality, if what you've done is free and isn't essentially an exact duplicate of the show (which my examples are pretty damn close), you'll likely never hear from them.
