NuKinja still allows us to dismiss comments!
I have to admit, I was skeptical of that feature when Kinja was first implemented Way Back in the Before Time, When There Were Stars, but I've got to admit:
Burner Account + Verbal Diarrhea = DISMISSED
is a winning equation in my book, especially because the mods got Reduced Powers because Kinja, and emailing Gawker because of a burner they'll do jack shit about is a complete waste of time.
All you need to do is mouse over the offensive comment until the gray arrow appears in the top right-hand corner of the comment. Click that, and it will show you a drop-down menu with all your options.
(Not that I would ever Dismiss x84jdh, this is just an example.)
I've gotten better at curbing my first instinct to argue back, and instead have cultivated a state of Zen Dismissal. It helps.
