Recently, I found a user had posted a complete copy of their credit card magstripe in a question on Security SE. As I did not have 2k rep on that site at the time I could not force an edit to hide the information.
I flagged the post, commented, edited, and tried to find someone on chat to help with this issue, but it took a while (~12 hrs), during which the complete card data was available (except for their name, which the user redacted, although they had a name on their account).
I reported the issue to the issuing bank, which should reduce the impact, but was this the correct way to handle this, and is there anything I should have done differently? Should a different procedure be followed for credit card numbers than for email addresses?
