Query: How Community Feedback Shapes User Behavior   Social media systems rely on user feedback and rating mechanisms for
personalization, ranking, and content filtering. However, when users evaluate
content contributed by fellow users (e.g., by liking a post or voting on a
comment), these evaluations create complex social feedback effects. This paper
investigates how ratings on a piece of content affect its author's future
behavior. By studying four large comment-based news communities, we find that
negative feedback leads to significant behavioral changes that are detrimental
to the community. Not only do authors of negatively-evaluated content
contribute more, but also their future posts are of lower quality, and are
perceived by the community as such. Moreover, these authors are more likely to
subsequently evaluate their fellow users negatively, percolating these effects
through the community. In contrast, positive feedback does not carry similar
effects, and neither encourages rewarded authors to write more, nor improves
the quality of their posts. Interestingly, the authors that receive no feedback
are most likely to leave a community. Furthermore, a structural analysis of the
voter network reveals that evaluations polarize the community the most when
positive and negative votes are equally split.
