Well, the mods have been locking a lot of threads recently, with a disclaimer that you might get a slap if you contributed. I'd ask the mod you think did it, why, and justify your case. Then they might get rid of it immediately. That's what I did when I got it once a few years ago.
...frankly I'm afraid I got one for posting twice in that Revenge thread.
Edit: nope, it seems I'm not.

That's when he posted, not when it appeared. It means a mod has to check what the post is and then approve it. It's not like it's posted any later.
