just be prepared with the usual requirements (20k cash, accommodation details, flight out, etc) and shouldn't be an issue. As others have mentioned it's always at the IO's discretion, but seems like it's the people living in Thailand on back to back to back exemptions and extensions that face the problems.
sounds like you'll be fine (depending on your history of course). Not sure why such an alarmist statement would be made without knowing any of your circumstances!
