How the scammer worked

1 Scammer posted job advertisements on Facebook and Carousell offering part-time work, which involved replying to texts.

2 When victims replied to the ads with their cellphones, they were told they would receive a text confirming purchase of game credits. They were told to reply "Y" for "yes", generating a code which they sent to the scammer.

3 Victims were told they would be reimbursed for the money they spent on the credits, and they would be paid for their work via bank transfers.

4 They would chalk up bills of hundreds of dollars to over $1,000 for the credits, which were then charged to their phone bills.

5 When the victims tried to contact the scammer about the reimbursement, he would be unreachable and they were left saddled with the bills.
