I’ve been in and back at least 60 times since 2011 and you gotta take out the 2 covid years. I’ve never had and issue but I only come for a holiday and I’m not doing border runs
I come to Thailand 6 times a year and generally for about a week each time. I’ve been doing this for about 15 years and the only comment I’ve ever gotten at immigration was a tongue in cheek “ Wow you really love Thailand”.
