This handbook was developed by
Reporters without Borders and has some really good information on setting up and using anonymous blogs, etc.
It was published in 2009, but I think remains relevant and is, I fear, not as well known as it ought to.

Reporters without Borders have published a "Handbook for Bloggers and Cyber-dissidents," with technical instructions and advice for people who want to use the internet as a means of expression in repressive societies. "Bloggers are often the only real journalists in countries where the mainstream media is censored or under pressure," they state. "Only they provide independent news, at the risk of displeasing the government and sometimes courting arrest."
The handbook provides tips on how to remain anonymous while blogging; explains how to publicize a weblog, and offers basic advice on ethical and journalistic principles.
