Cyberbullying: no place to hide
In an excellent cross-cultural study on Wikipedia edit/revert behaviours , Tsvetkova and her colleagues argue among other things for a mediating effect of culture in accounting for different dominance patterns to the editings in different language editions of the online encyclopaedia. The Wikipedia Humane-Machine Network is biased in some sense towards large geographical reach and network size, along with high human agency, low workflow interdependence, but low network organisation. And facebook, as highlighted in a previous post, also displays high human agency, again geographically disparate across a very extensive network. What might these vast networks with a great deal of human agency, but only moderate social tie strength do?
One area that is increasingly brought into focus, however, is cyberbullying . Individuals, especially those in public focus (Jonah Lehrer) or who might be expected to know better (Justine Sacco), may be subjected to the cascading effects of viral relational or indirect aggression in full view of the virtual world (Ronson, 2015 ). The vulnerable and impressionable, such as children, may be subject to grooming as well as aggression, with little chance of refuge , leading to potentially greater affective trauma especially in connection with real-world bullying . Situated within a generalised model of aggression , cyberbullying may be subject to similar social factors  as offline behaviours such as an assumed reluctance to intervene  and a diffusion of responsibility .
Perhaps the reality though, as underlined by the HUMANE profile for these networks, is that network size and geographical dispersion along with high levels of human agency and few controls (low network organisation) lead to what Suler had put down in part to the combination of dissociative anonymity, invisibility and the asynchronic nature of communication and interactions . The perpetrators of online aggression are not easily identifiable, when they hide behind pseudonyms and different online personae, whilst social contagion  creates the domino effect.
We might ask whether increasing Tie strength might mitigate against cyberbullying, by encouraging a shared understanding of its detrimental effects , facilitating participative discussion and understanding  and developing social identity which might encourage protective intervention . Networks with high levels of human agency, as well as large membership and geographic distribution will need to consider carefully how to handle potential problems therefore of latent or weak Tie strength. A number of strategies are possible (see the forthcoming D2.2). But for the unauthorised distribution of personal data and unwanted behaviours outlined here, the risk of not adopting those or similar strategies may be detrimental to the interests or well-being of human participants in the HMN.
