Crap downvoted you accidentally I dont think there is a problem of censorship for those not aware if a post is not viewed by lets say twenty people over set time it will be hidden. I think this also applies to old post but can be retaken or unhidden also. So i think that your post did not earn much attention. Just to be clear people may not be aware if thats the case for steemit social but i may also be wrong. Sorry again for accidentally downvoting but yes bubbles do burst.
