News Context: The science behind abandonment.  
Paper Context: The search volume on that date is 14%, showing the validity of the assumption that the maximum amount of active users corresponds to those with coreness above 0. Thus, these 10 million remaining users correspond to nodes with k s > 67. Given these two reference points, we can approximate the collapse of the network through its "unraveling" per k-core.
