Look at how Mexican narcobloggers do it. Many of their sites are hosted at places like Blogger. They keep backups of everything they write (those sites let you download site archives from your control panel). They access everything over Tor using TAILS. They delay what they post compared to what happened, to make it more difficult to correlate who was within range of an event (i.e., witnesses) and when they posted it. They don't post from home but go elsewhere.
They don't tell anybody they're narcobloggers. At all.
