Nah, it's not enough for a post and it's too intertwined with your post.
About the ads, I'm sorry I didn't get your initial message. I think the ads that display at frontends that use ad services (rent out ad space) that are somehow profiled by (at least) site's content. I believe you can see unrelevant adds because there's still not too many of them - we get only few types of advertisers, up for now.
I don't want any of the frontends to start using google ad services or any other that tracks and profiles users data/metadata. If the hive grows, we'll get more diversity in ads topics thus better ad relevance.
About the censorship part.
The hive was about the freedom of speech, freedom of being an asshole. It is very important for us, for me. At least it's what got me here. The world is filled with assholes and people who want to cut the corners. The hive/steem didn't overlooked that. It assessed the issue and provided the solution that did not revoke its stance about the freedom of speech and censorship disgust:
- downvoting,
- muting,
- frontend muting,
If your community gets a asshole, it's members can downvote him and mute up to a point a frontend will mute him, he won't get neither rewards nor audience (incentive to bee an ashole significantly decreased).
I remember reddit communities it was cancer, it still is. I use reddit once a month or even less frequently. I remember one fine example of it when some r/israel or sth like that published an article defaming Poles during WW2 based only on few Jews opinion (what's important they were not witnesses of any wrongdoing). Every comment trying to point out the historic research based data was removed. So the community tried to publish articles about Jews selling out Jews in occupied Poland, Nazi collaboration among Jews (there were instances of collaboration among both Polish Jews and Poles, but they were individual ones not shared not supported by majority). These articles were removed on pretext that they do not represent the community topic which was Isreael, not Jews [sic!] While at the same time the article about Poles and Jews in occupied Poland did not violate community's rules. And it happens everywhere on reddit and is supported by biased moderation and reddit owners...
BTW there's one idea that occurred to me, concerning your post - how to implement discussion while not messing up your profile with short irrelevant posts that you don't want people to visit your profile find in the first place (I want people to notice my first-class posts, not d.buzz twitter-like posts).
So there's an app by @revo https://d-hiver.herokuapp.com It's pretty dead right now, but all it does is create a one-time seed post and your next discussions are actually responses/comments to your seed post.
