The reason people are getting denied entry from borderruns/bounce is that exceptions are free, different visa types are not free. So everytime someone gets repeated excemptions, its money lost for Thailand. I made a day trip to Kuala Lumpur for a fresh 60 day excemption stamp. On return i had to do a 30 min interview with the officer, and after that she called my wife to verify. I just barely avoided a denial of entry. I was told, next time i would be denied, so she urged me to obtain the correct type of visa.
There is no guarantee this will work. I did a few border runs by air, the interviews are pretry intense. They even called my wife to verify the informatuon.
