The use of WhatsApp without the declaration of consent from every person in the user’s address book directory is deemed to be inadmissible in a recent decision by the family law department of a German lower federal court (AG Bad Hersfeld, 15.05.2017 – F 120/17 EASO).

The court held that the mother of an 11-year-old boy had to ensure and constantly control that all of her son’s phone contacts had given their consent to the transfer of their contact data to WhatsApp.

In India, an administrator of a Whatsapp group has recently faced arrest, following the sharing of what is alleged to be a defamatory photo-shopped image of Prime Minister, Narendra Modi.  South Africa has yet to test the liability of a group admin with regard to what is shared on their group.  However, given the rise in online racism and hate speech, paired with the millions of people around the world who use the Whatsapp application, it could only be a matter of time before a case like that in India comes before the South African courts.

Most people would not bring along a group of uninvited strangers to a dinner party or, even worse, a wedding. Society has certain expectations around attendance, guest lists, RSVPs, and the like.  And yet, in the digital realm, these social norms may not have the same effect.   What can be done about digital party crashers?  In particular, how can the owner of a social network ward off competitors who seek access to network content by riding users’ coattails?
