In recent years, the marketing literature has given considerable attention to the concept of online consumer misbehaviour. However, this increased interest has resulted in a significant accumulation of knowledge, leading to fragmentation and confusion in the field. This situation has serious implications for both researchers and practitioners, as it impedes the development of a coherent and unified understanding of the field. To address this issue, this paper presents a systematic review aimed at consolidating and organizing the available research on online consumer misbehaviour. The paper provides a conceptualization and operationalization of the concept of OCM. Additionally, the paper identifies and discusses the existing theories used in the field of OCM research.

With the booming popularity of social media such as facebook and Wechat, more and more people and firms commence to utilize it to promote products and services. The convenience of sharing personal experience online, however, also leads to increasing number of consumer to complain through online reiews. For example, negative online review has increased 800% over the years between 2014 and 2015 (Causon 2015) and has negative impact on many viewers’ buying decisions (Chevalier, & Mayzlin, 2006). Therefore, it is important to investigate what factors would reduce the negative impact of other customers’ online complaints on consumer purchase intention. Developing friendships with customers through social media is a common strategy for service provider to retain customers. Prior literature suggests that consumers in general are more tolerant of a service failure when the service provider is having a friendship with the customer than when the provider is having a business relationship (Wan, Hui, and Wyer 2011). Therefore, we suggest that friendship could also attenuate the negative impact of an online complaint from other customer on consumer purchase intention. Furthermore, we predict that this could happen only in the self-consumption situation. In the consumption situation of buying gifts for others, friendship would no longer attenuate the impact of a negative online review on consumer purchase intention. It is because gift giving involves sybolic value of face enhancement in developing social relationships with the gift giving target. Consumers would be less likely to take risks of buying substandard products as gifts. Implications and future research directions will be discussed.

There is a variety of mobile beauty application specialized services providing information, such as reports on the advantages and disadvantages of a product, as well as tips and recommendations, based on consumers' comments for products that demand much consultation on the part of the consumers to critique the products. From goods purchased through mobile shopping apps, beauty-related products come right after fashion/retail and food/health-related goods, while promotions, followed by review/comments, are known as influential factors when selecting mobile shopping apps. Consumer reviews about a product are seen as important instruments for obtaining a variety of information about a product for those consumers who have not yet used it. Moreover, there is an increasing interest in authentic information instead of purely advertised narrations, while studies are actively in progress to verify the effectiveness of consumer reviews according to their nature and direction. The results vary with each researcher and since online consumer reviews differ, there is a need to research dynamically blended reviews and the forms that they take. Accordingly, this study attempts to observe and identify the factors that affect the perceived authenticity of the information, brand attitude, purchase intention and electronic word-of-mouth (e-WOM). The sample consists of 110 respondents in their twenties and thirties who have purchased beauty products online. The respondents were given online and offline questionnaires, and the collected information was analyzed with SPSS 21.0 and AMOS 18.0 using factor analysis, reliability analysis, t-tests, structural equation modeling (SEM) and multi-group analysis. The results show that perceived information authenticity has a significant influence on brand attitude, purchase intention and e-WOM. Positive, negative and subjective evaluations have more significant impact on information authenticity than did only positive and negative reviews, while perceived authenticity has significant relevance to brand attitude, purchase intention and online word-of-mouth. The implications of these findings
