Flagging people absolutely does not equal censorship. The post is still going to be there regardless of how many times it is flagged. Aside from that, tags are necessary for people to find the kind of content they want and get rid of the kind they don't. Spamming tags completely ruins that and is rightly being flagged. That's the whole point of steemit, that everything is judged by the people. If the people are annoyed that there are many posts with the same content as other posts, they should be able to flag it.
