That depends. If someone with the power to silence someone chooses to do so, then no matter what label is attached to it, I'd say that person has been censored.
Let's say John Doe Steeminan (new account) posts comment X. Well, Joe Bloe Whale (with a few million Steem Power and a reputation score in the 80's because everyone upvotes his nonsensical posts hoping to score curation rewards or tickle his ego enough to make him upvote them) reads comment X and decides he doesn't like it (for no particular reason). So Joe Bloe Whale goes on a streak of going through John Doe Steemian's posts and flagging every one of them until John Doe Steemian's rep score is well below zero, meaning his posts now never see the light of day. John Doe Steemian has neither the power to defend nor retaliate.
This platform is one of the best ideas I've seen in a while but there's a reason the logo still says "beta" on it. I hope that there will be some way to iron out these bugs in the future.
