Advertising as PHD

I have come across a few therapists advertising as Bob Smith PhD LCPC And different other variations When I dig further, the PhD is in sociology some other field that is not Psychology. I feel this is misleading to people as even I was confused, but took the time to dig a little more. I think it makes it look like they are Clinical PhD psychologists when they are not. Is this ok by psychology advertising standards? Would this even fall under that? Or would it fall under therapist standards?
