The last name of the notorious "Usman Bello", much feared by Internet Scammers for his(?) ability to infiltrate criminal communication networks, reroute Western Union Transfers (WUxfer) and appropriating the scammer's victims.
Alternatively, the last name of an particular Government Minister in Nigeria.
He has recently become part of the Nigerian Internet Scammer's "Scam" format, placed next to the (hallowed?) presence of Miriam Abacha of Nigeria, and Wang Qin of Taiwan.
"I just recieved an email from Mr. Bello... should I respond?"
