 - The data collection was limited to public online communities to comply with the platform's privacy policy. 
 - We leveraged a [Pushshift Reddit API](https://reddit-api.readthedocs.io/en/latest/) to scrape posts from 40 subreddits daily across four different domains from Aug 24 to October 28, 2022, resulting in 104,674 posts. 
-- To enhance the ecological validity of the study findings, we used a PRAW API to perform another round of data collection of the collected posts 2 months later to validate whether the post content was moderated or not. 
+- To enhance the ecological validity of the study findings, we used a [PRAW API](https://praw.readthedocs.io/en/stable/) to perform another round of data collection of the collected posts 2 months later to validate whether the post content was moderated or not. 
 - Thereafter, we used a snowballing approach to collect the corresponding comments on all the posts.
 - The metadata includes post content, post time, comment content, comment time, karma score, etc.
 - We set a threshold for the minimum number of comments to 2 and an upper bound for the number of direct comments to 15 to facilitate the extraction of graph-based structural information.
