What you did was money laundering. And big chance for getting in trouble if let’s say ton of credits come from fraud/stolen and then google pays out to you and then crawl back once they realize is fraud.

I’m curious how you didn’t get into money laundering problems.

Technically it was an unregulated money transference service without KYC. The user that stole the cards from the bookstore was the one doing the money laundering part. I just enabled it (which is probably worse, legally).

I was investigated and cooperated fully.

Edit: I just remembered, the bank I used for the transference did do KYC for all users who were sent funds. This makes it more like "money dirtying", since the account is tied directly to a real identity.
