there is no reason to have doubt about what anonymous posters say. I don't like the fact that people post anonymous, but suggesting they do not tell the truth is unfair.
There are many millions of people entering Thailand, which means they can only check a very small part. Therefore they will try to check people with highest risk, and of those group still only a small percentage will be checked. Logical risk factors are types of visa which are abused much, people getting visa with visa run, people doing border runs. Using probability calculation will show how many people are checked never, and how many people are checked several times with the same chance.
Anonieme deelnemer 601 I do not really see a reason when you have non-o retirement in a legal way, why you should move to DTV, unless you are in the same situation I am in and don't like the inflexibility of the in country extension every year around the same date. And as long as you travel often out of the country the maximum 180 day stay is not really a disadvantage.
Financially the DTV is a bit cheaper in case you do workcation and do not have to spend extra money for soft power, but the differences are not very big and do not justify to have the DTV for that reason, because with DTV you have less possibilities like not opening bank account and only 2 years drivers license.
And when DTV keeps being misused the way it now does, you can also expect stricter checks
