Return Type: CSOM Boolean
The StopFollowing method removes the specified actor from the list of actors that the current user is following. This method returns true if the specified actor was removed from the list; it returns false if the specified actor was not removed from the list. For example, if the current user is not following the specified actor, the method returns false because it is not necessary to remove the actor from the list.
actor: Specifies the actor, which is a document, user, site, or tag.
