In social network environments, behaviors of actors are not independent [13], and joining a community provides one with tremendous benefits, such as members feel rewarded in some way for their participation in the community, and gaining honor and status for being members [14]. Therefore, every actor shall have the incentive to join communities. However, in the real-world scenario each actor not only receives benefit from the communities it belongs to but also needs to pay certain cost to maintain its membership in the communities [15].

In contrast, we apply gold questions as a socially responsible measure of workers’ trustworthiness to measure their skill level rather than as a discarding mechanism. Furthermore, monetary incentives as means of quality control have been investigated. But the implementation of such an approach proves to be tricky, where low paid jobs yield sloppy work, while high paid jobs attract unethical workers [16]. It is important to note how tightly coupled our work is with the IRT Paradigm [17] in psychometrics, which enables us to focus on the workers’ capabilities.
