Is There a Mod for Adding a Comment to a Post?

[FreshPrince]

Is there a mod for allowing a moderator or admin to post a comment at the bottom of a post? I don't remember if I've seen something similar or not with this done with rep, whereby a comment might be attached at the bottom of the post.



Basically, I just want a hack that will allow me to write a comment about people that I ban, rather than having to respond to them and thus bump the thread. I don't want to edit their post because then I can be accused of having fabricated the entire post. I just want to add a little comment onto a post that has already been made. I don't want to hit the "edit post" button on someone else's post. I'd just like to hit a comment button that then sticks my comment at the bottom of their post, perhaps underneath a line or in a box or something.

Does a hack like this already exist?

Thank you very much.
