Remember some of us are good not all scammers. Even though we raised as young child taught how to scam in many ways it is in our blood do not mean we all do it. So keep that in mind please.
You maybe have in mind to improve Nigeria image through this post but i find out that it is more damage than you think. Maybe you parents raise you through scamming if you said "is in our food" but i know many Nigeria that are good, have good moral behavior, never scam any one, return anything find that is not theirs, help others build successful career and helped many helpless people. Scamming is not in the blood of any nation and you can be scam by citizens of any nation. Scamming no , no nationality!
