No, this scammer is not associated with the forum and I don't even know if he has an account here...
I wanted to punish him somehow by sending another transaction with an indication in the notes that this is a fraudulent address but I think it's stupid...
If you the scammer not associated in this forum or if you don't know him personally, if you don't know his personal details/address then how you will punish him? Only one thing is left that you have to be another scammer and somehow you you scam him. LOL

This is also not perfect.
So now you should forgive him as Royse777 said. And Yeah Learn from this lesson and don't be fool next time.
