摘要

背景:随着直接面向消费者的基因检测服务越来越受欢迎,公众越来越依赖在线论坛来讨论和分享他们的检测结果。最初,用户是匿名的,但最近,他们在讨论结果时加入了人脸图像。各种研究表明,在社交媒体上分享图片往往会引发更多的回复。然而,这样做的用户放弃了他们的隐私。当这些图像真实地代表用户时,它们有可能泄露用户的身份。目的:本研究调查在线环境下直接面向消费者的基因检测用户的面部图像共享行为,以确定面部图像共享与从其他用户获得的关注之间是否存在关联。方法:这项研究集中在r/23andme上,这是reddit上一个专门讨论直接面向消费者的基因检测结果及其含义的版块。我们应用自然语言处理来推断与包含人脸图像的帖子相关的主题。我们应用回归分析来描述帖子收到的关注之间的关联,根据评论的数量,业力分数(定义为赞成的数量减去反对的数量),以及帖子是否包含人脸图像。结果:我们从reddit的r/23andme子版块收集了2012年至2020年间发布的1.5万多条帖子。人脸图片发布始于2019年底,并迅速增长,到2020年初,已有800多人公开了自己的脸。包括一张脸在内的帖子主题主要是关于分享、讨论祖先组成,或者与通过直接面向消费者的基因检测发现的亲属分享家庭团聚照片。平均而言,包含人脸图像的帖子获得的评论比其他帖子多60%(5/8),业力得分是其他帖子的2.4倍。结论:r/23andme版块reddit上直接面向消费者的基因检测消费者越来越多地在社交平台上发布人脸图像和检测报告。发布面部照片与更多关注之间的联系表明,人们正在放弃自己的隐私,以换取他人的关注。为了降低这种风险,平台组织者和版主可以以直接、明确的方式告知用户发布人脸图像的风险,明确表示如果个人图像被共享,他们的隐私可能会受到损害。

Implicit Incentives Among Reddit Users to Prioritize Attention Over Privacy and Reveal Their Faces When Discussing Direct-to-Consumer Genetic Test Results: Topic and Attention Analysis.

Background: As direct-to-consumer genetic testing services have grown in popularity, the public has increasingly relied upon online forums to discuss and share their test results. Initially, users did so anonymously, but more recently, they have included face images when discussing their results. Various studies have shown that sharing images on social media tends to elicit more replies. However, users who do this forgo their privacy. When these images truthfully represent a user, they have the potential to disclose that user's identity.

Objective: This study investigates the face image sharing behavior of direct-to-consumer genetic testing users in an online environment to determine if there exists an association between face image sharing and the attention received from other users.

Methods: This study focused on r/23andme, a subreddit dedicated to discussing direct-to-consumer genetic testing results and their implications. We applied natural language processing to infer the themes associated with posts that included a face image. We applied a regression analysis to characterize the association between the attention that a post received, in terms of the number of comments, the karma score (defined as the number of upvotes minus the number of downvotes), and whether the post contained a face image.

Results: We collected over 15,000 posts from the r/23andme subreddit, published between 2012 and 2020. Face image posting began in late 2019 and grew rapidly, with over 800 individuals revealing their faces by early 2020. The topics in posts including a face were primarily about sharing, discussing ancestry composition, or sharing family reunion photos with relatives discovered via direct-to-consumer genetic testing. On average, posts including a face image received 60% (5/8) more comments and had karma scores 2.4 times higher than other posts.

Conclusions: Direct-to-consumer genetic testing consumers in the r/23andme subreddit are increasingly posting face images and testing reports on social platforms. The association between face image posting and a greater level of attention suggests that people are forgoing their privacy in exchange for attention from others. To mitigate this risk, platform organizers and moderators could inform users about the risk of posting face images in a direct, explicit manner to make it clear that their privacy may be compromised if personal images are shared.
