### User Behavioral Patterns
#### 5.1.2 Posting and Commenting Behaviors Across General Users and Superfan Groups  
To address RQ2 (\"How do digital random activities vary across different user groups?\"), we examined the posts and comments and discovered numerous instances of exact text duplication. When we removed duplicate text from the same user, the total number of posts and comments decreased substantially, as shown in Tables 5 and 6. However, this effect was more pronounced for posts than for comments. For example, among the post-heavy users, the original 45,967 posts dropped to 20,114 after deduplication, a reduction of more than 50%. This decrease was much larger than that observed for general users or comment-heavy users, indicating that post-heavy users frequently submit identical posts multiple times. Many of these were large-scale promotional posts, referred to as a mass fan campaign, in which fans coordinate a particular activity such as information sharing, vote promotion, or stage whisper. For instance, some post-heavy users posted numerous invitations from third-party groups discussing BTS, as follows:  
_\"We would like to invite Y'll to BPB SCOUITS on TELEGRAM. JOIN: https://... let's have fun talking about our BANGTAN BOY'S and many more stuffs. This groups is safe and secure.\"_ (Posted more than 1000 times by several post-heavy users.)  
_\"Hello dear ARMY we created the group TELEGRAM for BTS ARMY GIRLS. To enjoy chatting with many ARMYs including foreign countries. We are there from all over the world. We are talking and sharing all the information, links, voting issues related to BTS.\"_ (Posted more than 1000 times by several post-heavy users.)  
Another example involves a promotional campaign that encourages fans to vote for a newly released BTS song or participate in a popularity contest, as follows:  
_\"please Vote for V - FRI(END)S song. please Vote for V - FRI(END)S song. Make him wins. we can do it fighting. [[https://en.funnstar.tf.co.kr/rank/view/wmusic](https://en.funnstar.tf.co.kr/rank/view/wmusic)]([https://en.funnstar.tf.co.kr/rank/view/wmusic](https://en.funnstar.tf.co.kr/rank/view/wmusic))...\"_ (Posted 26 times by one post-heavy user.)  
_\"!!ARMY!! please vote for [PERSON] - the most handsome man in the world 2024. He's now second position...\"_ (Posted 182 times by one post-heavy user.)  
We also found that many posts were nearly identical, differing by only a few characters. For example, some post-heavy users repeatedly posted countdowns to a BTS member's military discharge or tracked BTS's daily Spotify streaming numbers as a form of stage whisper, as follows:  
_\"I WAITING FOR YOU. MY LOVE \"D-Day\" on Spotify Counter Day 326--2,496,831...\"_  
In contrast, removing duplicate text from comments does not result in as large a reduction that as observed for posts. Even for post-heavy users, the total number of comments remained relatively stable after deduplication. Although the general and comment-heavy users showed about a 10% decrease, the post-heavy users exhibited only minimal reduction. This finding indicates that post-heavy users frequently re-post identical content but rarely duplicate their comments. We then investigated the duplicated comments and found that they tended to be simple, common responses. For example:  
\begin{table}
\begin{tabular}{l c c c} \hline \hline  & **General** & **Post-Heavy** & **Comment-Heavy** \\ \hline Post & M = 34.2 & M = 1209.7 & M = 119.1 \\  & (SD = 65.9) & (SD = 767.9) & (SD = 205.9) \\ \hline Comment & M = 71.3 & M = 281.8 & M = 3355.7 \\  & (SD = 189.8) & (SD = 633.9) & (SD = 1410.0) \\ \hline \hline \end{tabular}
\end{table}

\"what are you doing now\"_ (commented twice by a comment-heavy user)  
\"happy birthday\" (commented twice by a comment-heavy user)  
Overall, repeated content is more prevalent in posts than in comments, likely because the feed updates extremely quickly. As a result, users often re-post identical or very similar content to maintain visibility in the rapidly changing feed.
