## 5 Conclusions, Policy Implications, and Future Research
### Policy Implications  
On the basis of the above conclusions, in order to improve the privacy protection of the communities and promote user privacy disclosure behavior, this study proposes the following suggestions (Figure 6):  
(1) Improve the users' explicit benefits. On the basis of the actual situation, for users, the explicit benefits obtained from disclosing private personal information, such as higher-quality online medical services, rewards from the communities, etc., will lead them to disclose private personal information. Therefore, community managers should focus on the improvement of explicit benefits to users. Specifically, this firstly involves improving the quality of online medical services. For communities with online medical functions, community managers should deepen cooperation with medical institutions, medical schools, medical research institutes, and other institutions, integrate multiple resources, and improve the quality of online medical services as much as possible. Thus, when users disclose personal information, they obtain more accurate, comprehensive, and personalized online medical services.

For communities with online social functions, community managers should formulate a reasonable reward mechanism to provide richer material or spiritual rewards for users who actively share their private personal information or experiences through leaving messages, comments, and posts, such as giving a certain amount of vouchers or \"excellent user certification\" for highly active users, etc., in order to promote user privacy disclosure behavior. (2) The internal environment of the community should be optimized. A relaxing and comfortable social environment can enhance users' sense of belonging, promote communication and interaction between users, and effectively increase user willingness to disclose and share personal information in the communities. Therefore, community managers not only need to pay attention to the explicit benefits that users might obtain, but also to the optimization of the internal environment of the community. Specifically, this involves firstly strengthening daily management. Daily management has an important impact on the community environment. When the management is principally absent, a large number of conflicts and disputes, false information, marketing, and other violations can occur within the community. Therefore, community managers should consider selecting certain active users or opinion leaders from the community to form a special management team to assist them in daily management tasks, thereby improving the efficiency of handling violations. Thereafter, rules and regulations should be formulated. Community managers should formulate corresponding rules and regulations based on the community environment, and clearly inform users of their behavioral norms and legitimate rights and interests. The establishment of this system not only reduces the probability of violations within the community, but also provides a basis for the community management team to deal with various violations. (3) The additional costs of the \"positive protection\" strategy should be reduced. For the online health communities, implementing a negative privacy protection strategy only needs to meet the minimum requirements stipulated by national laws or local regulations, but implementing an active privacy protection strategy entails certain additional costs, which may be prohibitively high. Therefore, community managers should try to reduce the additional costs of the \"positive protection\" strategy in the following ways. Firstly, information systems and network equipment should be procured in a centralized manner. The implementation of an active privacy protection strategy in the communities is inseparable from the improvement of information systems and network equipment.
