With the natural resources, intellectual minds and industrialization in Nigeria our country is indeed a blessing to the continent but due to bad and corrupt leaders the country is becoming something else , the rate of crime such as kidnapping and internet fraud keeps increasing because of the hardship an unemployment situation, this isn't an excuse for all these atrocities but if there were opportunities most of them wouldn't think of doing all that... Nigerians are being stereotyped by other African countries due to the things Nigerians are involved in.. Nigeria is blessed but limited by bad governance
When you look dip into the Nigerian society, all of the things you mentioned happened across all states are guilty of this but let's not rush into conclusions, let's break it down. Nigeria marginalization was a mistake by the colonial masters, it was big mistakes because there is nothing like one Nigeria and this division is causing big problems in Nigeria, the Hausa, igbos and Yoruba are too different people that can't coexist.
Now let's forget about the ethnicity, there is too much religious differences among Hausa, Igbos and Yourba's, Yourbas are even religious tolerant but there is a huge difference between the igbos and Hausa. The literate ones tolerate each other but majority don't and that is the genesis of the problems we are having in Nigeria today, there is insecurity in the major North where Hausa live and there is high rate militant killings in the Southeast where major Igbo people stays but few in Yoruba land.
What am I saying, Nigeria was never a possible thing, it was force. What I have mentioned are the main problem and step back of this country while the rest you mentioned are secondary, they are popular because the primary reason.
