No. I think you misunderstood. There is no more explicit limit, but after a few entries, immigration can ask you what you're doing in the country.
Now, if you were to come and go regularly but spend only like a week in the country on each visit, spending MORE time outside Thailand than in, you'll likely be granted entry without questioning or incident.
The problem is, way too many foreigners are spending most of their time in Thailand on visa-exempt entries and then expect to be allowed to re-enter without trouble, almost as if they had a "right" to come back in. This is not so. Don't abuse the privilege.
Elías Molina I'm not sure the Department of Foreign Affairs, which is responsible for visa issuance abroad, has access to databases, which check for blacklisting etc
That's why we hear of people being granted Thai visas but then refused entry at the border.
While I don't think he has been blacklisted or has any ongoing legal issues, if I were him, I'd take the risk and show up at the Thai border, arriving by land from a neighboring country.
If one doesn't want to chance it or spend the money on finding out, then better don't come at all and find greener pastures.
It's all about what risks one is willing to take.
I personally think the risk of showing up, by land, from a neighboring country is minimal.
The OP talks about not wanting to "waste money", well, a lawyer would cost good money, applying for a DTV would cost money (applying from Europe, you pay irrespective of the result) and a plane ticket costs money.
If at the end of the day, the worst happens and you're refused entry, let's say, if coming from Malaysia, then just spend a couple of weeks vacationing there and go home. No big deal.
