This is the truth because when they started to approached you via email or pm, you need to be alarmed and automatically consider it a scam right away because they already calculated and have all the recipes once you reply to their message and you might even think that they were the best man in the world while they were acting. When they knew their victim is simple-minded, that's when they let you do things that you aren't even aware of it being scammed. The best thing to do is ignore and delete the message once you receive such kinds of offers.
