Spoofing has been taken to a next level art form. Even today, there are still people not technically adept either through age, inexperience, or that fact that we are not all created equal. I don't mean that in a bad way, it's just a fact or we would all be pro athletes. It's another reason I believe in limited distribution of wealth policies, we are created equal in dignity. Further even the very savvy get taken in by an excellent fake on rare occasions, other times perhaps they've been up all hours with a sick child and aren't thinking clearly. Let's not forget who the real villain is here... Unfortunately they are extremely difficult to catch as digital forensics is in direct opposition to rights to privacy. It's not something we're are going to resolve in the near future.
