Did a number of searches here and around google and no one seems to really be talking about it the way they did the Overwatch source film maker takedowns by Blizzard in May.
To cut a long story short, Nintendo seem to now be following suit and have started to issue DMCA take down notifications to remove pornography from tumblr blogs. While the bulk of the Overwatch take downs seemed to at least be related to missuse of Blizzard's own art assets in source film maker - an act that at least can be justified by content creators essentially reusing Blizzard's own work - Nintendo's notices don't relate to 3d animation of their owned assets but rather extends to just any created content.
No reddit link on this one, sources is uh ... my own inbox:
What are your thoughts, GAF?
Edit: For clarification's sake, it seems like the most recent wave of DMCA claims specifically related to Princess Peach.
Edit 2: Content of a non-pornographic nature hosted on pornographic tumblrs also seem to have been removed.
November Update: Zelda has now been caught in a wave of DMCA notices.
