What is the legal status of secret societies?
Some assumptions on these societies to restrict the question:
1) They are not involved in unlawful activities in the countries in which members operate.
2) They may be concerned about politics or religion.
3) They operate online. (This point raises the further question: under which jurisdiction they would be regulated?)
4) By secret I mean: they want their members, activities and operations to be concealed to non-members. They want the organisation itself to be unknown.
