Read my reply. I literally said that. Oh and what Thai government website should they check? Unlike some countries that have a unified government website that various departments of government use the Thai websites are generally controlled by a specific government department. The Ministry of Foreign Affairs (MFA) handle selling of visas worldwide. Immigration handle entry policies, and so on.
For a general question about is it 60 days or 30 days for a visa exempt entry it’ll be pot luck if you find an official source.
That’s why these Facebook groups exist. Because those in the know, know. Laws/rules and stuff change rapidly. Many times quicker than official websites can keep up with.
