It is not yet known whether the most important persons of this Scam have been arrested, but the fact that the scammers are systematically sent to prison makes me happy.
This is indeed a good news, defrauding people of more than $3 billion is a huge scam which should be frown at at every sane level and it's really great seeing Chinese authority takes up the mantle to make sure the Mastermides behind the scam are taking behind bars. I hope the scam victim will be compensated no matter how small
