Table 2. Open coding of interview data on visibility experiences of A-friends.

Category and original statements (example) Coding
Self-reconstruction
 In the beginning, you really need a self-awareness process, and fellow patients on Weibo can indeed provide various information. [H17] Self-awareness
 Some people record their health status and medication intake on Weibo to help manage these aspects themselves. [H7] Self-health management
 But I probably wouldn’t post my daily feelings and life updates on this platform. [H16] Sharing personal life
A relational bond
 Later I remembered Weibo exists, so I searched there and eventually found the A-friends. [H18] Community searching
 On Weibo, when you follow someone, it showed other related users. By checking comments/likes under their posts - especially those with “A” symbols, “Ai” emojis, or medication start dates - you can find many “similar people.” [H26] Show other A-friends
A form of power
 When an A-friend with Kaposi’s sarcoma posted a help request on Weibo, hundreds of us reposted it, creating a significant impact. [H6] Public rights advocacy
 We repost to amplify voices against injustices. [H25] Public rights advocacy
Ego depletion
 Seeing pessimistic content repeatedly, like fellow patients encountering misfortunes, makes me anxious about myself. [H15] Pessimism
 Sometimes I feel deserving of the accusations. [H18] Self-stigmatization
 Unconsciously comparing myself with active/finding partner community members makes me feel inadequate or even envious. [H30] Self-comparison
Privacy concern and misinformation
 My Weibo was found by real-life friends, colleagues, and classmates despite blocking phone number access. [H3] Privacy anxiety
 Some community members post private photos or inappropriate content in Weibo groups. [H29] Inappropriate content
Limitations of public visibility
 Weibo’s polarized public opinion shows extreme attitudes toward (HIV+) people. [H18] Extreme remarks
 Some netizens’ harsh comments are irredeemable - why attack patients so viciously? [H21] Extreme remarks
