I find it weird that they just took down the site and took over the twitter account during a search. Nothing has been ruled illegal. It’s like if someone sued Google and decided to take the search engine down during the initial search for illegal material. How is this legal? And even if the site is deemed illegal, how does that allow them to hijack his twitter account?
