Notice that there isn't any reply button, (at least I can't see one). How did someone just reply to the thread, (and others), then? Should this hole get closed, or again, is there some sort of secret override of which I should be aware?

Not only was my reply not rejected, but oddly, it got posted to an entirely unrelated thread from '09:

Something very odd is afoot here.
