Do my parents have a right to control me as an adult?

I am a adult in my 30's and my parents are still very controlling even when I am on my own and don't live with them. They treat me like a child and tell me not to post on Facebook or use my account because it's personal. I know I have a disability but they do not have power of attorney or do not look after me. They tell me they will find a way to take my account away and that I will be in a lot of trouble or that they will make sure I get the proper help I need if I go about their wishes. Is this normal behavior of them and do they have any right to do this? Even when I refuse and say I don't have to listen to them and that I am an adult with doing what I want as long as it is legal and doesn't violate the terms, they still say they need to get involved and that I need to listen to them or there are going to be consequences. One will be taking my account away and two will be them never supporting me again.

What should I do in a situation like this?

No, they don't. And unless you're engaging in behavior that is self-destructive or harmful to others, I think it's disgusting that they threaten to take away support if you go against their wishes, especially since you're disabled and probably don't have that many options as far as income is concerned. I don't understand why some parents feel the need to keep their children under their thumbs, even as adults.

They do not have the right to control you as an adult.

Apparently they do have the right to control you.
