The effects of CFSMIP on both perceived usefulness (H6) and continuance intention (H7) are surprising, as these results contradict with the past literature reviewed. CFSMIP was found to have significant positive effect on perceived usefulness, which is against the hypothesis developed. This suggests that one's privacy concern in mobile social commerce environment increases his or her perceived usefulness on mobile social commerce. Besides, the result also implies that for those users with higher privacy concern, they would perceive mobile social commerce to be more useful, in contrast with those with lower privacy concern. Tan, Qin, Kim, and Hsu (2012), who found that privacy concern moderates the effect of perceived usefulness on behaviour intention to use social networking sites has provided some relevant insights to this result. They discovered that the effect of perceived usefulness on behavior intention is stronger for the group with higher privacy concern, and they explained that the decision for this group to use social networking sites is mainly depending on perceived usefulness, so as to justify the potential loss of privacy. In addition, CFSMIP was also found to have no significant influence over continuance intention to use mobile social commerce, which is again against with the past studies reviewed. However, this result conforms to the study done by Tan et al. (2012) and Zhou (2012). Tan et al. (2012) reasoned that this result might explain why SNS users are still continuing their usage, even after some reports and incidents of privacy violations have been exposed. All the evidences indicate that social media users nowadays are inseparable from social media use, and this study has made extra confirmation to this phenomenon. Concisely, as social media has blended into our daily living, CFSMIP is unable to stop users from using mobile social commerce. In spite of potential privacy loss, users with higher privacy concern tend to value perceived usefulness higher, with the purpose of justifying their continued usage. Moreover, this also explains the partial mediating effect of perceived usefulness in the linkage between CFSMIP and continuance intention.
