This article examines the emerging paradigm of user-customizable algorithms in digital platforms, advocating for a shift towards user empowerment in content curation. By analyzing the limitations of current algorithmic curation, including echo chambers, misinformation proliferation, and lack of transparency, it introduces the concept of "write your own algo" as a solution. The paper reviews the literature on the discontents of algorithmic personalization, user empowerment, and bot detection, highlighting the need for more transparent and user-driven approaches. It presents a theoretical framework integrating algorithmic transparency, participatory design, user autonomy, and information ecology. The article proposes that user involvement in algorithm customization leads to increased satisfaction, engagement, trust, and content diversity while improving bot detection and content integrity. It discusses potential challenges such as cognitive overload and the technical complexities of user involvement. The conclusion emphasizes the importance of ethical, user-centric system design in digital platforms and calls for future research to empirically test and refine the propositions made. Show less

In an era marked by rapid advancements in artificial intelligence (AI), traditional CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) systems are increasingly vulnerable to sophisticated AI techniques. This paper explores the necessity for CAPTCHA technology to evolve in response to these advancements, specifically advocating for the development of CAPTCHA in Graphics Interchange Format (GIF). The study begins by detailing the challenges posed by AI to current CAPTCHA systems, highlighting how advancements in machine learning and computer vision have enabled AI to bypass traditional text and static image-based CAPTCHAs. In response, this paper proposes GIF-based CAPTCHAs as a viable solution. The dynamic and mutable nature of GIFs introduces complexities that challenge AI capabilities while maintaining user accessibility. A case study conducted by the author illustrates this point: ten GIFs containing unexpected elements were presented to both human participants and the GPT-4 AI model. While human participants could consistently identify and describe the twists in the GIFs, GPT-4 failed to recognize these elements, indicating a significant gap in AI's ability to process dynamic visual content with non-linear elements. This finding underscores the potential of GIF-based CAPTCHAs in maintaining digital security against AI-driven threats. The paper further delves into the technical considerations and developmental challenges of implementing GIF-based CAPTCHA systems, such as ensuring user-friendliness, accessibility, and compatibility across different platforms, while continuously updating the system to counter emerging AI techniques. The conclusion emphasizes the necessity of ongoing innovation in CAPTCHA technology, suggesting future directions including AI integration in CAPTCHA design, exploration of other dynamic media formats, and the use of behavioral biometrics.
