The text of every post is stored, along with up votes and down votes and other metadata. However, photos and videos are not actually stored in the blockchain.
Once in the blockchain, it can't be removed or censored. So, what's a government to do? They can't require the impossible. Best they could do would be to order Steemit not to display certain data found in the blockchain, but they couldn't require it to be deleted and they couldn't censor it.
I assume that if Steemit gets a DCMA notice they can and would stop displaying the offending data on their website, but it would still be on the blockchain, and I'm sure there will eventually be "dark" versions of Steemit, or dark blockchain browsers/explorers, that will make available an uncensored view of the blockchain for those who really want to see it.
That sounds like a recipe for a massively bloated blockchain. are the posts at least compressed in some way before being added to the blockchain? if steem is meant to be comparable to reddit then it should be prepared to handle similar amounts of data, according to a source I found one month of Reddit comments is about 30GB, so how is steem expected to handle that much data (steem will actually need to handle more data then that due to the overhead caused by including cryptographic proof with each comment, upvote and edit) without becoming semi-centralized (limited to a small group of big miners)?
also how are edits handled? a complete copy added to the blockchain each time an edit is made or just the changes?

I believe the whitepaper discusses scalability, but supposedly it's scalable to at least Reddit levels with current technology and specs.
I don't know regarding edits. Good Question.

@hell2o, I was wondering the same thing about edits. Did you ever find the answer?
