Anarchopedia is an online wiki that was founded in September 2004. As per anarchist principles, the wiki does not have a hierarchical structure (dividing users into administrators, bureaucrats etc.), but allows anyone to contribute constructively, yet many prolific editors are given access to special rights, such as blocking, to protect the wiki from vandals. Autoconfirmed users can delete/restore and protect pages. It can be very hard to tell the difference between regular users and admins.
Anarchopedia is present in about 30 different languages like English, Italian, Spanish, German, Swedish etc.
