If a post contains inaccurate information it would not be ideal to mark it "Unhelpful". Instead, you should reply to the thread by posting the correct information. If there were a Helpful button your more accurate reply should attract clicks.
If I do receive an Alert indicating that a post is inaccurate (rather than misplaced or disruptive) I either post a reply as described in the previous paragraph, or contact the poster and suggest an edit, but anyone could contact any poster by PM (unless the member has opted out of the feature) to suggest an edit.
So, it's really not an unhelpful button, then is it? It's a, "this post is in bad taste, harassing, violating TOS, etc." button, isn't it?
I may have misunderstood, but I believe
Kipper asked about what a moderator does if the existing
Alert function is used to report an
inaccurate post.
Opinions are neither accurate nor inaccurate. I ignore
Alerts which express disagreement with an opinion. I act on
Alerts which report inaccurate factual content, but I do not edit the post directly.
I asked about it, because you said that it already serves as an "unhelpful" button, but in clarifying your answer later, it really doesn't serve as that.
