I do not thinking censoring content is the way to go - much rather implement new filters and options for people to customize their feed. If you would rather not see NSFW content you should most definitely be able to opt-out, but to completely banning it is not an approach I support.

I do not think we can successfully stop people from shamelessly trying to attract upvotes - it happens on every established social media in existence. What we can do, however, is to promote a culture which values quality content whilst allowing users to seamlessly customize their personal feeds.
