TL;DR
DECIFE is a novel framework that detects collusive users involved in blackmarket following services on Twitter by analyzing user relationships and linguistic features through a sophisticated graph-based learning approach.
Contribution
This paper introduces DECIFE, the first method to identify collusive users in blackmarket following services using a heterogeneous network and attention-based graph learning.
Findings
DECIFE outperforms existing methods in detection accuracy.
The framework effectively captures semantic relations between users.
Experimental results validate DECIFE's robustness and effectiveness.
Abstract
The popularity of Twitter has fostered the emergence of various fraudulent user activities - one such activity is to artificially bolster the social reputation of Twitter profiles by gaining a large number of followers within a short time span. Many users want to gain followers to increase the visibility and reach of their profiles to wide audiences.

In this paper, we propose DECIFE, a framework to detect collusive users involved in producing 'following' activities through blackmarket services with the intention to gain…
