Abstract

Users in online social networks naturally organize themselves into overlapping and interlinked communities that are formed around common identity or shared topical interests. Some communities gather people around specific deviant behaviors, conducts that are commonly considered inappropriate with respect to the society’s norms or moral standards such as drug use, eating disorders, and pornographic content consumption. From a network analysis perspective, the set of interactions between members of these communities form deviant networks that map how the deviant content is shared and consumed. It is commonly believed that deviant networks are small and isolated from the mainstream social media life; accordingly, most research studies have considered them in isolation. We focus on adult content consumption networks, which is one deviant network with a significant presence in online social media and in the Web in general. We investigate two large online social networks and discuss the following insights. Deviant networks are limited in size, tightly connected and structured in subgroups. Nevertheless, content originated in deviant networks spreads widely across the whole social graph possibly touching a large number of unintentionally exposed users, such that the average local perception is that neighboring users share more deviant content. Finally, we investigate how content production and consumption vary with age and show that the consumption rate is very similar between male and female users up to the age of 25. We conclude that deviant communities are deeply rooted into the relational fabric of a social network, and that a deeper understanding of how their activity impacts on every other user is required.

Notes

  1. Flickr users can mark their own photographs as “adult”. We first attempted to use this self-reported information to detect adult photographs. We found that this approach leads to many false positives, mainly because very often pictures are marked in big batches containing adult and non-adult pictures.

  2. Louvain is a modularity-based graph clustering algorithm that shows very good performance across several benchmarks (Fortunato 2010) and that is fast to compute even on large networks.

  3. Link directionality is considered: ties originate from groups listed on the rows and land on groups listed on the columns.

  4. The number of samples in each age distribution is high; therefore, as expected, all the differences between the average values are statistically significant (\(p<0.01\)) under the Mann–Whitney test.
