Looked into this because I have never heard of it.
Based on some forums it appears that often stolen credit cards are used to buy redeemable codes. Those codes are then sold for far less... Basically washing the stolen CCs.
Hacking individual accounts seems much more difficult / less rewarding financially.
People sell accounts that are from phishers and botnets. Which is mostly less work than using stolen CCs
You can buy the accounts for $2 or you can pay $20 for unlimited accounts. They sell programs that you click a button and it just gives you another hacked account from their database.
Accounts that apply these codes typically have the subscription removed when the inevitable chargeback occurs though. I had this happen buying a code off Ebay due to not being in a supported Netflix country. Luckily Paypal was able to refund me.
