Can my wife continue entering Thailand on a regular entry visa while making frequent visits?

The user is inquiring about their wife's ability to continue entering Thailand on a regular entry visa while making frequent visits (up to twice a month). Commenters suggest that as long as she has proper documentation, such as evidence of accommodation, financial means, and onward travel, she should not face issues with immigration. They also mention that there are no official limits on visa-exempt entries by air, and one respondent recommends considering a METV (Multiple Entry Tourist Visa) if concerned about the frequency of visits.
