Why was I denied my stamp at the Malaysian land border while re-entering Thailand on a DTV?

The post discusses the reason for being denied entry into Thailand at a Malaysian land border despite having a DTV (Digital Nomad Visa) for the first renewal. Various community members speculate that the denial may be related to the author's travel history or the nature of their work, as entry can be refused if one admits to working while on a tourist visa. Several commenters recommend securing a proper visa suited for their travel intentions and caution against mentioning work activities during entry.
