One user signs up, asks how CDN works, we tell them that we usually don't permit CDN on sites that are not directly hosted by ourselves but we'd allow it in this one instance out of simply being nice people to the client.
12 hours go by, 20-30+ sign ups all from China with all off-platform hosted websites and some that were directly going overboard and using 20TB+ of bandwidth.
Unfortunately, one ruins it for the many. Our integration is now being modified to block all off-platform usage and all orders for CDN from users in China will be manually reviewed until then.
