Yeah the Ireland and Scotland ban was definitely because of the accent and it would have been fine if they had stated the reasoning as such, but they released a press statement that Ireland, Scotland, and South Africa are not native-english speaking, which of course is wrong.
It's good that you took your education so seriously and judging by your writing I can see it was certainly a success!
Thank you for the nice comment. The truth is that school helped me a lot and for a good reason. I hope Thailand with realize these banned please can help a lot.
....although, in fairness - Whenever I went to Glasgow - I couldn't understand a f****** word they were sayin' lol
