How the boundaries between countries affect cyberspace?

The boundaries between countries affect the online activities and liberties of the citizens. Some countries disallow online gambling and the use of certain social media websites is banned by the government. What may be perfectly legal in one country is illegal in Another Country.

For example, in Germany it is illegal to sell, show or exhibit Nazi material or paraphernalia (indeed for the 2006 World Cup, held in Germany, English football fans were specifically warned against taunting the locals with Nazi salutes or goose-stepping, not only because it would anger the locals, but also because it would land them in jail). Also, prevailing cultures and opinions differ between countries and arguments between people of different countries can take place over different issues. People in the Middle East may have very different opinions on "The War Against Terror" than those in the West.
