What are the current requirements for entry into Thailand without a visa for frequent travelers?

The user shares their experience of entering Thailand without a visa for the eighth time this year, mentioning a brief stay of 7-14 days per visit. They were asked to show their bank account details and their occupation as a pilot, which led to no issues at entry. They note that having multiple visa runs close to the exemption limit could raise red flags, contrary to the situation experienced by the user, which seems to indicate that the scrutiny is applied selectively, especially for frequent travelers.
