I did, most people do not meet the requirements.
BUT that is not the fault of Immigration but the choice of DTV holders.
Example: Group expert tells people that 500.000 Thb in your bank account can be used by multiple people, which leads to not meeting the requirements for an Extension of Stay.
Other example: 6 months course is not enough to apply for an Extension of Stay as the course ended before appllication.
I read group experts, but that does not mean they have a clue about Immigration rules, the Admin (not immigration) named them "expert",
