Always seemed to me that the correct response to this scam is to recruit everyone you know to go through just the first step of the scam and then quit while they’re ahead. Like taking a casino’s offer of free food and then leaving without gambling.

IIRC they chat group was using LINE, where the scammers can delete messages / kick people at will. So more people joining just to make a few bucks from the initial payout just increases the credibility of the operation.

Also the initial "tasks" the mark performs are worth only like a few USD. not worth anybody's time except for certain types of vulnerable people who not-coincidentally make good victims.
