As far as I know, Frebitco.in isn't banned anywhere. At least I haven't heard about such cases. But I wouldn't be surprised if one day they will be banned in some countries. First reason why is obvious - gambling is illegal there. But they can be banned because some kind of regulations too. For example they may be required to be registered in that country and pay taxes there, while Freebitco.in is registered in offshore. Just because of it almost all foreign sportsbooks were blocked in my country.
