No posts are censored on the Steem blockchain mind you. Steem is censorship resistant. So assuming a drug company is silly enough to plunge millions of Dollars to buy Steem (Moon!!), they'll only be a whale. downvote all they want, the only damage is a $0 pending payout and a collapsed post. Which can still be viewed if the readers want to.
not making money off a post isn't "being censored". So why be afraid of censorship?
I think making a post go grey so it looks like spam and nobody sees it is censorship. And taking all the rewards from posts that you disagree with is also censorship.
Both of which are happening to posts that expose the evil truth about vaccinations. It's already happening with just one or two small whales doing it.
What would Moby Dick do?
The BitConnect article flagging was pretty big a few months ago. It seemed to only affect people who weren't whales.
