Germany has many laws which are different that e.g. the USA. In particular, in the US certain sentiments which are politically and socially radioactive are protected by the US Constitution and the laws, traditions, and expectations of the American polity. Germany is similar in some regards but there is one particular politically and socially radioactive statement you could make -- support for the Nazi Party -- which, owing to the laws, traditions, and expectations of the Germany polity, will result in the government coming down on you like a ton of bricks.
I know Germany and many other countries in Europe are more sensitive about promoting extreme viewpoints. My question was more about something specific related to censoring blogspot, and how the domain redirects are used to bypass that. I mean, how does it matter what domain is used to display the same content? OP says he's redirected to blogspot.jp - what problems does it solve for Google?
> * how does it matter what domain is used to display the same content?*
It only displays the same content if that content is compliant for the local region.
Thus, in the Nazi example, all off blogspot get the posts except blogspot.de, who filter it out somehow.
That's something that Youtube doesn't do with adverts very well - I'm in the UK, I've not left the UK, my IP geolocates to the UK, but I often get US ads in Youtube. Advertising law is different and often the ads are not compliant for the UK.
