Hi, I'm Nigeryan Roielty! AND I NEED YOU TO SEND ME MONEY! Please ignore the fact that I can't spell Nigeria... or Royalty.
There's these websites where "scambaiters" actually respond to these 419 scam messages from Nigeria and basically pretend they're interested and make them waste all their time, and eventually do hilarious stunts for their amusement, usually in the form of pictures. They do this to get the scammers to "earn the trust" of the scam baiter. the goal of this entire exercise is to a. expose scams, and b. to make scammers waste their time responding to these guys who are in no way interested and mainly are trolling.
