Does being denied entry into Thailand after multiple visa exemptions lead to a ban?

A South Korean passport holder faced entry denial after utilizing six visa-exempt entries to Thailand over the past 18 months. Despite having no overstays, the immigration officer suspected intentions beyond tourism, leading to speculation about a potential entry ban. Commentary from the community suggests that while they were denied entry, this does not equate to an official ban, and future entry may still be possible through alternative crossing points. Recommendations included applying for a proper visa like the METV and ensuring documentation such as cash, proof of onward travel, and accommodation are available. Observations were made regarding changes in immigration rules that may affect entry practices.
