Abstract: Due to high camouflage of current spammer, classic spammer discovered algorithms become no longer valid. Same with real users, spammers can also form a network structure. This paper proposes an algorithm based on the network relationship to find spammer group. The first step is to find a typical spammer account as seed. Then it extends fans’ relationship step by step and searches account which occurs frequently to get a collection which contains a large amount of spammer accounts, according to the clustering of the relationship between spammers and the characteristics of the sparse nature between spammer and real users, using Fast Unfolding algorithm to community detection. Through experimental analysis, the method can well find spammer group.

Key words: spammer group, network relationship, community detection
