you're spot on about the visa market. This is why anyone could do border runs and fast track for years without a single denial (to essentially live in Thailand non-stop), as long as they respect the trial/upgrade business model.
The 'rules are rules, get valid visa' NPC brain people with laminated DTVs can't possibly understand this, or why anyone would pay to be let in every time without worries.
No crackdown. Just business.
