1989 anti sap crisis in nigeria caused by fake news

I think there may be some confusion here.

There was no "anti-sap crisis" in Nigeria in 1989 caused by fake news. SAP stands for Structural Adjustment Programme, which was a set of economic policies implemented by the Nigerian government in the 1980s to address the country's economic crisis.

The Structural Adjustment Programme was a real economic policy initiative, not a crisis caused by fake news. It was introduced in 1986 by the military government of General Ibrahim Babangida, with the aim of reducing Nigeria's dependence on oil exports, promoting economic diversification, and increasing foreign investment.

The SAP program involved a range of measures, including devaluation of the naira, reduction of government subsidies, and liberalization of trade and investment. While the program had some positive effects, such as increasing foreign investment and promoting economic growth, it also had negative consequences, including increased poverty, unemployment, and inflation.

It's possible that you may be thinking of a different event or crisis in Nigeria, or that there was a specific incident or issue that was misreported or exaggerated, leading to a crisis of confidence or misinformation. If you could provide more context or clarify what you are referring to, I'd be happy to try and help you further.
