I repair pcs and deal with people in these situations often enough and you are right. Many don't listen, and they think they are too smart to be scammed. Not true for all of them but some of the racist ones get scammed by the people they are racist against and I believe it is because they don't think they can be fooled by the people they hate, so they follow their directions in the scam....

You can get out of so much trouble just by knowing you are capable of being fooled. By knowing things that sound too good to be true, probably are. And above all else, do not fall in love with people you havent met. Everybody should know that, but unfortunately that's a tougher for some.
