We probably blocked access from his country because our licence does not cover it.
We have several countries blocked from accessing our site.
Do you have a list of countries that are blocked by PrimeDice/Stake or what countries your license extends to? It's weird. I can use PrimeDice and Stake fine, but sometimes I get ads for other sites and they say they're blocked in my country (not bitcoin gambling sites but other sportsbooks or casinos).
