Combating Friend Spam Using Social Rejections

Qiang Cao, Michael Sirivianos, Xiaowei Yang, Kamesh Munagala
2015 2015 IEEE 35th International Conference on Distributed Computing Systems  
Unwanted friend requests in online social networks, also known as friend spam, have proven to be among the most evasive malicious activities.  ...  We argue that our design, which leverages the aforementioned graph cut, can reliably detect a region that comprises friend spammers.  ...  Since the social graph is held on the workers, the master needs to fetch the social graph structure via network I/O.  ...
