Nuisance messages, a form of unsolicited communication, often occurs between drivers and users of online transportation application services. The transmission of such messages represent a violation of privacy, infringing upon users' autonomy to control the information they receive and potentially causing both psychological and physical harm. Despite the fact, Indonesian law lacks explicit normative regulations addressing nuisance messages. Facing this condition, online transportation application services must must ensure user safety by providing a mechanism for users to object and avoid receiving such messages. This study aims to address two primary questions. Firstly, what forms of legal protection are currently available against nuisance messages under Indonesian positive law? Secondly, how can online transportation application service providers implement the right to object in order to optimize the protection of user privacy and personal data? This study employed a juridical-normative method with descriptive analysis to address the questions. The results indicate that Indonesian positive law can only refer to whether messages are sent in good faith and whether spam messages are sent in bulk. These can cause misinterpretation for providers and users. However, nuisance messages sent during the provision of a service demonstrate bad faith on the part of the driver. Therefore, to protect users, online transportation application services should implement a right to object through an electronic contract, thereby granting users greater control and balance.
