He said why: "it gets blocked where the law allows such". I appreciate the link since it's blocked for me.
Annas Archive is blocked in some countries (like mine, Germany)
Netherlands also.
Depends on the provider I think, it's blocked for me on Youfone (KPN), but IIRC when I used Ben (Odido) it worked fine. It also loads just fine on my university eduroam wifi.
