User interactions in massively multiplayer online role-playing games (MMORPGs) generate social networks and diffuse user behavior throughout the network. We test the diffusion model in the adoption of a game bot among players connected via goal-oriented communities using real data provided by a major MMORPG company. In the model based on a probabilistic diffusion process, we used expectation maximization to infer the diffusion probability of game bot usage. The experimental results showed that the diffusion model can explain the spread of malicious behavior.
