What should the US do to combat Nigerian con artists?

Personally i haven't fallen victim to one but they have tried to get me multiple times through continuous emails and a few attempts scamming me on ebay (recently they tried twice to get me to ship a PS3 to a Nigerian address by sending me fake emails claiming that i had recieved a paypal payment - I'm sure they fooled alot of people with them).
20/20 recently did a study - and found over 100 million dollars had been successfully stolen over the last year.
Should the US quit sending aid to Nigeria until their government takes a more serious approach?
Does our government need stricter laws or more focus on enforcement?
Should Americans simply quit buying Nigerian products or going there on vacation?
What do you think is the best approach?
Answers:
Its simple. Just have the FBI send a warning to all active email addresses in the US (they already have a list) warning people not to fall victim to this scam.
I really don't feel sorry for any of the idiots who thought that they could send their personal information to some anonymous person in Nigeria and not get scammed by them.

Maybe we should educate the American people so that they are not dumber then a box of rocks. I have received several of these e-mails over the years and I can not believe anyone is gullible enough to fall for them. I feel it's time that the American public quites crying to the government and learns to take responsibility for thier own actions.

I think the best approach is for people to use common sense.
Why would someone you don't know email you from Nigeria and ask for your personal banking information and/ or money?
You can tell whether or not you've received a PayPal payment pretty easily and/ or whether or not you've sold something to someone in Nigeria.
Sorry, anyone that falls for these things just needs to THINK.

Track them down and finish them off with brutal technique, in order to scare future con artists from doing this

Do not let greed get in the way of common sense.Most people fall victim because of greed.Remember,if it sounds to good to be true,it usually is!

Other than education, there is nothing the govt can do.
First of all, most of the current "Nigerian" scams are not coming from Nigeria. The emails are originating on servers all over the world -- Nigeria is just the common setting for the scam -- but England and India are becoming equally common settings (though the emails still aren't coming from there).
And I don't think punishing the entire Nigerian govt or the entire nation's economy is the right answer, when the problem is caused by individual criminals. Since 80+% of the spam in the world comes from the US, that would be like refusing to do business with the US until the US govt stops that activity. It's not effective as a solution.
