I mean your earlier point is already wrong. A tourist visa or visa exempt entry whilst not having a limit. Does not permit you to live in Thailand. It's very clear on the conditions of entry.
People come in and out plenty of times. It's extremely common to start encountering issues after about 6 months of back to back entries. It's very very widely reported, I have personally experienced this like clockwork. Border run companies use specific borders and pay people off. It's Thailand, have an encounter with the police and you'll experience the same thing. Very common....
