Before now administrators of various WhatsApp groups find it difficult to handle people who post incriminating contents into their groups. In many cases admins have to call on those who post the content to delete same or be penalised.
But recent changes by WhatsApp allows admin to permanently delete messages posted to the group by any user for all users, using the delete for all button which was hitherto only available to the person who posted the content to the group.
This will give WhatsApp admins sweeping powers over what is allowed to be in their groups and what is not. But as the popular saying goes, "to whom much is given much is expected".
With the recent powers then some jurisdictions have the right to punish admins who refuse to delete incriminating contents which are criminal in nature, against group policy or found to be provocative.
Henceforth admins have the responsibility to delete threatening message or messages considered hate speech, inciting, drug related and the likes of and failure to do so can attract sanctions depending on the jurisdiction.
What is unclear is the definition of a competent jurisdiction considering the fact that WhatsApp groups do have membership and admins drawn from different jurisdictions due to its virtual nature.
