You can get scammers from anywhere in the world... no point in stereotyping a country, or any other group of people. The only takeaway here is that you need to do your due diligence before working with others. Sending money as friends and family is like giving a random person a few dollars to do an errand... Nothing to behold them in doing it, or recourse made avail if they don't.
It sucks, but it shouldn't be an excuse to start stereotyping a group of people like that.
