Thanks, Matt... But it's pretty evident from your customer support tickets that your customers were alerting you to this issue (and their privacy concerns) since at least 2011... But you've clearly done nothing to fix it since then.
It's hard to believe you take customer privacy very seriously when you've made evidence to the contrary so easily searchable in Google.
And this customer support ticket shows a customer complaining about the fact that their order information is visible on the internet. This was back in 2011.
ClickBank has to have known about this hole for years and hasn't addressed it.
