Say someone scammed you or someone you know and you know you can scam them back.
Would you do it? Why/why not? What do you feel?
If someone tries to scam me, maybe I will try to get back my money form that scammer or worst, I will find a way to scam that scammer back so that scammer would taste the bitterness of what he/she is doing to a lot of people, sometimes they need a taste of their own medicine so they could stop all the wrong things that they were doing.
