I have been using the various content-review options, and trying to flag things as appropriate.
However, I got a response to a comment on a answer where I never left a comment!
It seems that if I flag a question as "Not a real answer" using one of the content-review mechanism, it automatically adds a comment:
This does not provide an answer to the question. To critique or request clarification from an author, leave a comment below their post - you can always comment on your own posts, and once you have sufficient reputation you will be able to comment on any post.
Using my name, without being obvious that it's going to auto-insert something using my name.
While I think adding a "Add this pre-defined comment" button for people with enough rep, adding such a comment, and particularly making such a comment using my username, without asking or clear notification that this is going to happen is a very bad idea.
I'm generally OK the idea behind this function (and I do think that something in it's vein is actually a good idea), but I think it should be a separate button, or similar. The flagging and the automatic-comment-insertion should be two separate options, so if someone else has already added such a comment, or in a situation where (such as the example above), where the OP was basically saying he did what was detailed in the original answer, and it worked.
Clarification
My issue is mostly that the SE forum software is impersonating me without letting me know that it is impersonating me, and then putting words in my mouth. I really dislike it when a computer/whatever does something claiming to be me without at least indicating it's going to do so.
Basically, I log on today, and someone is responding to an automatic comment that the SE software made in my name that didn't appropriately address the issue at hand. If I had known the forum software was going to make such a comment, I would have deleted it, but I was never notified that it was happening.
