### Explanation Personal interests and preferences are fundamental aspects of human behavior and identity. In the digital age, these interests drive engagement with specific platforms, communities, and content. Businesses capitalize on this by creating targeted platforms and services catering to particular interests, from hobby-specific social networks to specialized marketplaces. This commercialization of interests has led to the development of: - Niche social platforms for specific hobbies and activities - Interest-based recommendation systems - Targeted advertising networks - Community forums and discussion boards - Content curation and sharing platforms The digital footprints left across these interest-specific platforms can provide valuable insights during investigations, revealing patterns, connections, and potential locations of individuals or organizations. ### Examples {{some links to articles, videos, etc}} ### Types - business - behavioural ### See also - [[SOWEL-17.
