# Social Network of Extreme Tweeters: A Case Study

## TL;DR

This study analyzes extreme Twitter users, revealing that anomalous users with high posting volume tend to have low content diversity and strong within-group interactions, highlighting distinct social behaviors.

## Contribution

Introduces the 'interest narrowness' metric and characterizes the social and content behaviors of anomalous extreme users on Twitter.

## Key findings

- Anomalous users have very low topic diversity.
- Anomalous groups show strong within-group interactions.
- Different sharing behaviors observed between anomalous and non-anomalous users.

## Abstract

The number of posts made by a single user account on a social media platform Twitter in any given time interval is usually quite low. However, there is a subset of users whose volume of posts is much higher than the median. In this paper, we investigate the content diversity and the social neighborhood of these extreme users and others. We define a metric called "interest narrowness", and identify that a subset of extreme users, termed anomalous users, write posts with very low topic diversity, including posts with no text content. Using a few interaction patterns we show that anomalous groups have the strongest within-group interactions, compared to their interaction with others. Further, they exhibit different information sharing behaviors with other anomalous users compared to non-anomalous extreme tweeters.
