Steemit is not censoring content. What is more than likely happening is that there are some members who disagree with you, and are down-voting your posts/comments. Unfortunately when that happens, if they have a higher reputation rating then yours, your post becomes hidden and in fact, your own reputation can drop a little.

PS. I just scanned through all 185 of your posts for the last 3 years, and found that only 1 of them has been hidden, and that one was because of a downvote as I suspected, so I really do not see what you are complaining about. None of your posts have been censored, and only 1 of 185 of them has been hidden, which in reality is not hidden at all if you know how to view it.
