Yes / This research aims to identify users who are posting as well as encouraging others to post low-quality
and duplicate contents on community question answering sites. The good guys called Caretakers and
the bad guys called Reputation Collectors are characterised by their behaviour, answering pattern and
reputation points. The proposed system is developed and analysed over publicly available Stack
Exchange data dump. A graph based methodology is employed to derive the characteristic of
Reputation Collectors and Caretakers. Results reveal that Reputation Collectors are primary sources
of low-quality answers as well as answers to duplicate questions posted on the site. The Caretakers
answer limited questions of challenging nature and fetches maximum reputation against those
questions whereas Reputation Collectors answers have so many low-quality and duplicate questions
to gain the reputation point. We have developed algorithms to identify the Caretakers and Reputation
Collectors of the site. Our analysis finds that 1.05% of Reputation Collectors post 18.88% of low quality answers. This study extends previous research by identifying the Reputation Collectors and 2 how they collect their reputation points.
