This question already has an answer here:
Often on meta sites I'll see questions asking about specific posts or users, which, for the most part, are fairly unbiased and fair. However, sometimes these posts can spiral out of control into personal attacks.
Should users that are the topic of these discussions be privately or publicly notified if they are the center of such debates? It would allow them a chance to explain actions or clarify things if need be.
I don't think all cases where a specific user is involved needs a notification back to the OP, but possibly things involving suspicious behavior on part of the person in question?
