I used to delete extraneous "HAY THIS IS SPAM OMG LOCK THIS THREAD" posts when I moderated larger forums. I could find, and lock, spam threads easily in forums with hundreds to thousands of new posts each day -- so I think the moderators that browse a small forum like this are pretty sure to not let stupid threads go unnoticed.
That said, I think everyone can agree that you can stop bolstering your post count or trying to appear like a vigilante forum patrol with superfluous "OMGZ SPAM THREAD" posts.

I'm just tired of every pointless thread that gets posted getting five or so immediate replies that all amount to "This is spam, and not funny, moderators should lock this imho." Guess what? No one cares.
