This chapter examines I Paid a Bribe (IPAB) as an empirical case of an informative ICT designed to address everyday corruption through civic participation and transparency. Rather than treating IPAB solely as an anti-corruption platform, the chapter analyses it as a sociotechnical infrastructure that converts dispersed citizen experiences into structured public knowledge. Applying the two-tier framework introduced in Chapter 1 , the chapter shows how IPAB foregrounds transparency through crowdsourced reporting, while grappling with challenges of reliability, equity, and social entropy in participatory data environments. Drawing on interviews, document analysis, and platform data, the chapter demonstrates how IPAB functioned as a civic audit architecture that reshaped the informational relationship between citizens and the state. The analysis also highlights the fragility of such initiatives, underscoring the conditions under which participatory transparency can meaningfully contribute to governance reform.
