It sounds like you were viewing the “new” tab?The hot/active tabs on Kbin wouldn’t receive that content so early. It will always be a wackamole game, no platform will ever succeed 100%. Once there are more advanced moderation tools, I would suggest silently removing objectionable content or users.
Also, I’ll have to disagree slightly, thats not a lot of interaction. This single post alone has over 300 upvotes since posted. The volume of either is simply an indication of how strongly people react.
