You have 1000 Billion dollars. So what do you not need your fund which is on your right? No one can give up those 400$ dollars without any valid reason. The person has become scammed 400$ dollar which can't be considered spam, revenge, or something like that. Hence it is the right of that person to claim that 400$ and also it is his right to let people know about the scam.
What? I don't understand what you are trying to imply here. If you're trying to state that I am such rich dude who treats 400 bucks like it's nothing, you are completely wrong. Reread my previous post thoroughly.
What I meant to say was that 400 bucks meant a lot for that particular victim and he has every right to try and reclaim his funds.
