@ivan Maybe show the number of flagged/reported posts?
Usually when I see many posts being flagged it's a sign of the thread going wildly off-topic or even attracting bad actors. I then stay away from that discussion. However, e.g. in Discourse I won't know until I have read through the posts. Having that metric on the top post would help me spend my time and engagement elsewhere.
Thinking of risks, maybe showing flag stats would attract more of the same? I would hope not in an otherwise functional community, but some people seem to gather around car crashes or houses on fire.
