I think that flagging a post that had several hundreds SBD in rewards is to be considered curation, not censorship.

In our local elections, in addition to voting for a party, we used to have the possibility to both upvote and downvote individuals. In order to "protect" individuals, the possibility to downvote was removed. Who benefits? That's the most well-known politicians, those who get most media time, those who are most noisy and get heard the most. Earlier they would get the most upvotes and a fair share of downvotes. Now they only get the most upvotes.

The same applies to Steem. I can understand that it may be unfair that a novice making his first low-quality post gets flagged, but it's totally reasonable that someone that gets a three-digit reward on a post also gets a fair share of downvotes.
