some traders might not really care, but this is not just about the person; they also do this to others. Before the end of a day, they can easily scam someone or even more than one person.
Some may actually not care, but if its not tackled now, they will keep doing it and more people are going to be cheated under their attempt for scam, it was because they have tested it to see how some already fall a victim before deciding to continue, now we have to make others get the necessary awareness on related routes to scam in this manners.
The awareness is indeed necessary; it will help make many aware of this type of trader on P2P, and the more people are aware, the more their attempts will continue to fail, and it will start discouraging them from doing it if they see that fewer people or no one is falling victim to that, their pity, and whatever excuses they use to deduct and reduce the amount they are supposed to send to the seller just to be gathering them up.
