Let's suppose that a certain user makes me wonder if he/she should be trusted or not and I wish to discuss this on meta. Perhaps some people would recommend flagging right away, but the idea is that I'm not sure if the person in question is doing something wrong.
However, if I decide to make a post that implies some sort of public shaming, which is not quite right. How should I address such situations? Can one talk about such a thing here without problems?
