You're believing the fairy tales - your choice. I deal only with facts, and there's been enough information provided by Thailand Revenue (not Facebook "experts), that in my case, and probably thousands of others, all money remitted to Thailand is exempt from taxation.
I'll be here for more than 180 days, but I'll be a dual tax resident, so I'll use the DTA test to establish Australian Tax Residency, which for my situation is quite easy, and confirmed by Thailand Revenue. Plus any money I bring into Thailand is exempt taxation.
