If you'd like, I could create a simple scenario.
Pretend I am a spammer. I realize mods are asleep and I make a spam thread. The thread gains a few pages, then I lock it. It goes well into the third or fourth page of the forum by the time the mod shows up, so he never even notices it.
See what I did? I created a spam thread and caused uproar on the forums, yet got away without a scratch, and could later return and do the same thing once again.
This is only implying that I can't unlock the thread, which the OP never mentioned, thus, I never mentioned in the scenario.
Fact of the matter is... there are cons, like the one I posted above, but like I said, the pros outweigh them, if I must say so myself, significantly.
