Ebola is in Nigeria. This means that it must be wise to donate, without the expectation of return, to the Nigerian Princes so they can fund the search for a cure and create grants to save lives. Do you note care about Ebola in Nigeria? Do you feel that heartless?
There are no Nigerian princes. Nigeria is a republic. So if someone claims to be a Nigerian prince he's not one. It's always a scam. "Son of the President" would be more believable but without some serious confirmation I wouldn't believe that one either. Still most likely it would be a scam.
There hasn't been a single one of these scams where any one has gotten paid. There is no such things as free money and if something sounds too easy to be true it most definitely is. No one gets something for nothing. Facebook needs to do more to prevent these scams.
No, it is not wise to give money to Nigerian princes, because they probably won't give it back to you. Did you know that in Nigeria to be a prince all you have to do is sit in a room with the internet and lack the morals to cheat other people? Beware Nigerian princes on the internet.
First of all I don't think it is wise to give money to any organization that you have not done your due diligence on. Meaning, it does not matter if it is online or not, you have to make sure where your money is going, what percentage actually goes towards the cause they claim to be helping and if the organization is legitimate. Additionally, with all the scams on the Internet and Facebook lately, you have to be even more cautious.
Facebook has become a place of many scams. It is not wise to give money to Nigerian princes or to anybody over Facebook for that matter. A huge question I have is, if these men are Nigerian princes then why do they need your money in the first place? Normally people of royalty are already wealthy. That should sound like a scam and make someone not want to send their money.
