chandra: We never store your card details directly in our database. If a card is saved, a secure, encrypted token is created for future use, therefore there is no need for us to keep the actual card details.
GameRager: Good to hear, but anyone who logs into such an account with info saved could buy games on that card tied to that account. So a fix for the bug would be welcomed.
Also: Please start keeping track of replies ton posts you/others have made and reply to them if possible. Many replies to staff after the first staff reply in a thread get no answer...even when staffers are still logged in and should notice them. NOte this kinda depends though
On steam, while you are able to save your payment method, steam still requires the CCV code when you checkout. This means that even if your account is hijacked, unless the hijackers guesses the CCV they can't buy anything with the account
I havent bought anything on GOG in awhile so I don't know if GOG asks for the CCV on purchases, which would aleviate said concerns
Also why are you using bolded text. If you're concerened people are misinterpreting your intent, don't bold your posts which from a perception perspective looks one step down from all caps.
If I had to guess what the problem is, it's likely similar to the web caching issues Steam had during Christmas
