I think posts #delete would be useful, although i realize it's hard to implement it, votes has to be returned, security question arraises too.
But a solution could be to create a "Post archive" for each user. So when post is deleted, it's not actually deleted, but placed in Post Archive, this will keep things consistent but will allow to remove trashy and unwanted posts from #steemit as well as google index.
pros:
cons:
Can this be a future request, what do you think steemers?
