Why was my post about Thai visa entry decline?

That is the question this group usually doesn't allow to post.

There is no written rules on how many you can enter on tourist visa or visa-exemp by air. The only written rule is two times of visa-exempt entry par calendar year.

BUT,

It is another story if you are approved to enter Thailand on tourist visa or visa-exdemp as approval your entry is at the discretion of the immigratio officer at the passport contol upon your entery to Thailand. He may let you in or he questions you if he thinks you travel to Thailand too often. And only that officer can answer if you would be approved to enter Thailand.

All you can do is being prepared with proof of onward travel tickets, proof of accomodation, and proof of funds of 20K baht cash or equivalent in major currency per person or 40K baht per family along with the explanation about you being genuine tourist, if you want to travel Thailand often.
