One South African abalone exporter has described sophisticated methods of corrupting customs officials in order to facilitate illegal exports. Rather than simply offering direct bribes, the exporter had assistants track an official's personal habits, discovering the official frequented a particular casino weekly. The exporter began providing credit vouchers for the casino, allowing the official to "have some fun." After establishing this pattern of gifts, the exporter requested "a favour in return" – allowing abalone shipments safe passage through the airport without inspection. This calculated approach to corruption highlights how wildlife trafficking networks identify and exploit the personal weaknesses of government officials.
