This is brilliant.
It also appears to be working.
Corruption kills social contracts, kills citizen participation, kills representative government, kills progress, kills justice.
It's one small step. Making it patently clear to those taking bribes that they are corrupt is one small step.
Corruption also simply kills: it kills by selling medications from hospitals; it kills by taking money needed for clean water; it kills by diverting money from the public to the private sector.
Corruption isn't limited: it is pervasive when those corrupted can hide and not be called to account.
