Artist didn't want people uploading their art to other sites, and filed a cease and desist to Danbooru. People kept on uploading despite that using an exploit so they just nuked all of their various accounts (Pixiv, Tumblr, Twitter).
Well, that's just my guess as to why they did it. It could've been for another reason other than people reposting their art without permission, but that's the only one that comes to mind. I know a lot of Japanese artists get annoyed with that.
