there is NO limit whatsoever on visa exempt entries. Let’s be clear about that.
The absolute dogshit AI quote you posted here is irrelevant. 1- there is no such things as misuse of visa exemptions. There is the system that immigration built. 2. There are no ‘penalties’.
And what gets ‘reported’ has to be taken with a grain of salt. Thailand has 40 million annual tourists. 1000 people being denied is hardly a developing story. There are always people who make mistakes..
If you are using visa exemptions for legit tourism, you will have no issues at all
if they were denied entry, they had something significant in their history, or in their travel patterns. There is nothing at all wrong with extended tourism. Thailand loves it. As long as you can show you have the money. If they think you are trying to live or work there, it’s a different story. You may be questioned on arrival, by immigration officers just doing their jobs. May even be given a warning for next time. But not denied
