This article explores student perceptions and attitudes towards aberrant Internet consumer behaviours (ACB) and examines cross cultural differences in E-consumer ethics. Data gathered from 365 students from more than five different cultures - Taiwan, China, Indonesia, Malaysia, the U.S., and the U.K., and a group of other countries - were compared in this investigation. The respondents from Southeast Asia displayed the highest E-ethics while those from China exhibited the lowest. Most respondents spend 2 to 5 hours a day browsing the internet. On average, the students from Taiwan displayed the highest E-ethics. A high percentage of the respondents thought ”Illegal and Questionable activities” are wrong; while a lower percentage considered factors of ”Human Internet Trade” and ”Downloading Material” are wrong. The result shows that Machiavellianism was significantly and negatively related with to E-ethics, while consumer attitudes towards the Internet were not significantly related to E-ethics.
