Also to access certain types of media - more and more sites are blocking non-native IP's. The DR certainly isn't on many watch lists however, like dv8 says most folks its a work thang.
The site I mention in my previous post can give specific geographic regions...east coast, midwest, west etc...handy little tool. Works for Windows, Mac and Linux (I used Linux and it's huge to have support for my OS).
depends on what you mean by censorship. some videos will not play for people in DR (unavailable in your country). some sites detect your IP and also do not display info. when a friend was booking her flight with kayak (USA-poland) she had different flights displayed based on the same search (she's in chicago) than me in DR and another girl in warsaw.
