This study examines the legal and interpretative challenges in identifying commercial elements within text-based pornographic discourse on social media, particularly in distinguishing pornography from sexual insult and commercial sexual exploitation. While prior research has focused on regulatory frameworks and electronic evidence, limited attention has been given to the role of linguistic structures in revealing implicit commercial intent. This research employs a normative juridical approach integrated with forensic linguistic analysis of publicly accessible social media texts, utilizing lexical categorization, pragmatic implicature, and speech act analysis to identify structured indicators of commercialization. The findings demonstrate that commercial sexual elements cannot be determined from isolated expressions but must be inferred through the convergence of transactional diction, intermediary references, and economic-motivational framing within a coherent discourse. The study further confirms that not all sexually explicit or offensive language fulfills the legal elements of pornography, thereby requiring careful doctrinal differentiation to prevent overcriminalization. Linguistic indicators contribute to interpreting potential actus reus and mens rea, yet their evidentiary value remains complementary and must be supported by formal legal proof. This study offers a structured analytical framework that bridges forensic linguistics and criminal law, enhancing evidentiary precision while upholding the principles of legality, proportionality, and freedom of expression in digital law enforcement.
