You can probably confirm whether or not those sites are actually blocked/banned by your government. Just try asking your internet service provider. They should be able to clear that up for you. Is bitcoin illegal in your country by the way?

And yep, same as the others, the only reason I sometimes can't access some of those sites is when there are problems with my connection or a problem with the site.

Anyway, again, I suggest confirming with your service provider. They should know if a site is blocked/banned/illegal. It's always better to be sure. Can't just assume things.
