A similar topic has come up in other groups as well. Most notably the writing groups were many people have decided that the fiction tag can be used for just about anything.

I have read that there are fixes (hivemind) being considered and worked on which might address your issues to some extent.

I agree that having more granular control over where the posts go would be a HUGE step forward in usability. I would take it a step further and have a place where users can hide things based on certain tags. Or at least place them in "circles" like G+ did. That way my feed isn't filled with the twenty steemhunt, or one line posts from busy, but the content isn't censored per-say, just not out in front.
