What countries is KuCoin restricted in?

Could you please elaborate on the countries where KuCoin is restricted? I'm particularly interested in understanding which specific regions have imposed limitations or bans on KuCoin's services, and what the reasons might be behind these restrictions. Is there a comprehensive list available that outlines these countries? Additionally, do these restrictions apply to both individual users and businesses seeking to utilize KuCoin's platform? It would be helpful to gain a clearer understanding of the geographical scope of these limitations.
