Does Amazon actually end up charging you when this type of thing happens or do they eventually wipe the bill after you talk to support? If Amazon tried to charge me, I would definitely be in touch with the credit card company I have attached to the account. This is rather straightforward fraud/identity theft so you should be covered by the standard consumer protections most credit card's provide.
I accidentally posted AWS credentials to the AWS EC2 forum, and got > $10k (US) of charges very quickly. They removed all the charges immediately, without me pushing at all. They offered it.
That is good to hear, but it also means the headline is a little on the click-baity side. This is a bug that caused a lot of headaches and cost time to fix, not one that cost $6,500.
