A bit too much of fear mongering about 1 year ban. Never heard before.
Since years they tell that you won't be able to pay tax/insurance with an open ticket.
Since years others tell you it's just hot air, don't care, don't pay.
I will not try to find the truth tentatively.
I think it is worth to change the address in the book.
Might be a PITA with certificate of residence.
There is website in Thai to check for outstanding tickets.
But only usable with Thai ID, so not worth linking,
