TITLE: Antisocial Behavior in Online Communities

ABSTRACT: User contributions in the form of posts, comments, and votes 
are essential to the success of online communities. However, allowing 
user participation also invites undesirable behavior such as trolling. 
In the talk I will discuss antisocial behavior in three large online 
discussion communities by analyzing users who were banned from these 
communities. We will find that such users tend to concentrate their 
efforts in a small number of threads, are more likely to post 
irrelevantly, and are more successful at garnering responses from other 
users. Studying the evolution of these users from the moment they join a 
community up to when they get banned, we find that not only do they 
write worse than other users over time, but they also become 
increasingly less tolerated by the community. Our analysis also reveals 
distinct groups of users with different levels of antisocial behavior 
that can change over time. We will use these insights to identify 
antisocial users early on, a task of high practical importance to 
community maintainers.
