censorship - What is scaring and what is not?

Just had an interesting email exchange with people at the Berkman Center at Harvard Law School. They conducted two years ago an investigation into the Chinese filtering system of the internet. The tone was a bit hush, hush, and they promised not to reveal my name to anybody.
Hold on, I said, I have been writing myself and RSI-arm about these issues and you want to keep my name secret?
What I fear most at this stage is not whether I get into problems here in China. My main worry is whether I get into the US next month again without pretenting I'm an accountant.
