In this case, the guy with the problem is living outside of the country in question. He would still have access to Twitter but the people causing him problems potentially wouldn't.
My personal background includes a parent who grew up in Germany during WW2 and its aftermath, a parent who was a two-time decorated veteran and an ex boyfriend whose political activism cost him 3 years in prison in his youth. He was questioned under torture.
