Query: Large-scale analysis of grooming in modern social networks   Social networks are evolving to engage their users more by providing them
with more functionalities. One of the most attracting ones is streaming. Users
may broadcast part of their daily lives to thousands of others world-wide and
interact with them in real-time. Unfortunately, this feature is reportedly
exploited for grooming. In this work, we provide the first in-depth analysis of
this problem for social live streaming services. More precisely, using a
dataset that we collected, we identify predatory behaviours and grooming on
chats that bypassed the moderation mechanisms of the LiveMe, the service under
investigation. Beyond the traditional text approaches, we also investigate the
relevance of emojis in this context, as well as the user interactions through
the gift mechanisms of LiveMe. Finally, our analysis indicates the possibility
of grooming towards minors, showing the extent of the problem in such
platforms.
