Abstract: This research aims to identify users who are posting as well as encouraging others to post low-qualityand duplicate contents on community question answering sites. The good guys called Caretakers andthe bad guys called Reputation Collectors are characterised by their behaviour, answering pattern andreputation points. The proposed system is developed and analysed over publicly available StackExchange data dump. A graph based methodology is employed to derive the characteristic ofReputation Collectors and Caretakers. Results reveal that Reputation Collectors are primary sourcesof low-quality answers as well as answers to duplicate questions posted on the site. The Caretakersanswer limited questions of challenging nature and fetches maximum reputation against thosequestions whereas Reputation Collectors answers have so many low-quality and duplicate questionsto gain the reputation point. We have developed algorithms to identify the Caretakers and ReputationCollectors of the site. Our analysis finds that 1.05% of Reputation Collectors post 18.88% of lowqualityanswers. This study extends previous research by identifying the Reputation Collectors and how they collect their reputation points.
