Well, it depends what you call censorship. The thing is you can post anything and nobody will hinder you to post things. But of course users (and bots) can rate (upvote) or flag it.
I just have a problem with steepshot. A user probably accidentally flagged a perfectly beautiful picture that I took yesterday in Prague with my smartphone. But because it is flagged it won't show in my profile in steepshot any more. It is still visible in steemit though. But in the eSteem app it showed a -1 vote. That's why I upvoted it myself so it won't show a -1 any more. So I also think it is not okay, when just one user can cause a picture to disappear. I think it needs more people to flag something before it gets unavailable. If a new user like in my case flags a picture or other content it shouldn't have such a negative effect.
This is the picture I'm talking about:

I think downvotes should only count if at least 5 people downvote. And a person who downvotes a lot, their downvotes shouldn't count much any longer.
Thank you for sharing your experience. And thanks for letting me know about Steepshot! Didn't know about the app :)
But, yes, the issue that you bring up is a real one. Right now it's too easy to downvote/flag someone and make their content disappear. Some reform is needed in this area. That's what I mean by people's content being censored.
