Where is Paxful not allowed?

Could you please elaborate on the regions or countries where Paxful's services are not accessible or permitted? It's important for users to understand the geographical limitations of cryptocurrency exchanges, and Paxful being a popular platform, its reach and restrictions are of particular interest. Are there any specific regulations or legal frameworks in these restricted areas that prevent Paxful from operating? Additionally, are there any plans or efforts underway to expand Paxful's services to these regions in the future?
