Data collection of drug abusers in online communities

We crawled all the post data on the "Dynamic
Control Bar" forum. The main fields crawled included user name, user
nickname, main post name, post name, posting time, and post content. The post
content that was irrelevant to this study, such as advertising information,
abnormal information, and pictures and videos, was removed. Including the
removal of irrelevant advertising posts and meaningless posts, 7524 posts were
finally left as the data source for this study.
