Which method of acquiring expertise might indicate potential criminal activity?

Acquiring expertise by recruiting illicit knowledge from unauthorized sources is indicative of potential criminal activity because it often involves accessing information or skills through illegal means. This method typically entails learning from individuals or platforms that may be involved in criminal enterprises, thereby fostering a culture of secrecy and illegality. Such knowledge is usually not available through legitimate channels, suggesting that the individual may have intentions aligned with unlawful actions.

In contrast, formal education courses, online tutorials, and volunteering for community programs are legitimate methods of learning and developing skills that typically contribute positively to personal development and community engagement. These avenues emphasize ethical learning and often have structures in place that promote integrity and legal compliance.
