Yesterday saw quite a number of people taking advantage of the HHonors Gold trick that I provided. But I've just been told that someone who accidentally registered their account to Taiwan successfully got their Gold status too.
For the record, when I tried on my own UK registered account, it didn't work, but there might be other factors at play. Problem is there is a limit of somewhere between 5-10 tries before the Visa Infinite page stops letting you try for a few hours.
If anyone succeeds with any other countries (whether intentionally or not!) then please leave a comment below.
