It isn't censorship. It is a few people being assholes.
Steem-blogging lacks property rights and the freedom of (dis)association. You don't have the ability to disengage with people. And that's why steem-blogging cannot work. When 5 mentally unstable people can ruin the experience for thousands of other users, it's just going to fail.
The silver lining is that tribes (and hopefully communities) do have property rights. If someone is being a jackass on palnet or steemleo or any of the other tribes, they can just be muted by the community leaders. So while steem-blogging can't work, tribes and communities at least have the possibility of working.
