Wrong. Some entry points should either be avoided (if you're on a particular visa) or particular caveats may apply, in order to avoid being scrutinized by immigration. These may include - being a frequent traveler on a DTV being much better than someone who only does a quick border run every 180 days to avoiding the entry point as much as possible.
Practically anyone who knows the Thai immigration system well, including experts on here such as
@James *******
will advise people to avoid the Aranyaprathet-Poipet border crossing for entry into Thailand (obviously, not relevant now as the border remains closed...but whenever it reopens, this advice will apply). I advise people it's OK to use that border crossing provided you're driving your own vehicle and are the driver of said vehicle, since drivers can stamp in outside, where immigration is more straightforward than the ones inside the arrivals building. Anyone who is coming on foot or by bus, or by private car where the driver is Thai or anyone but themselves should avoid that crossing, unless they are on an LTR visa, marriage or work visa with work permit.
Why? Since 2015, when the Bangkok shrine bomber bribed immigration there to come through, they've been VERY tough, on any tourist or any foreigner not on a long-term visa extension.
Perhaps the CNX airport scrutiny towards DTV holders isn't quite as bad as what happens to foreigners on any short-term visa at Aranyaprathet, but the reports are frequent enough to be of a concern and thus warrant that caution be exercised.
