Every week in Nigeria
The class rep sends a WhatsApp broadcast: "Please pay ₦2,000 to Chidi — 0123456789 GTBank." Chidi spends the next two weeks manually checking his bank alerts, cross-referencing names, chasing people with DMs, fronting money himself when the deadline passes, and watching three people in the group privately suspect he kept some of it. Nobody wins. This happens every single day across millions of Nigerian groups.
