Yes, it does. If you put 999 in the search box and search by keywords, it appends the word liar to 999 and returns no results. Even if you click on the keyword 999 in the keywords of this thread of yours, it does the same thing. I know JR thinks Cain is an okay guy, so I can't imagine he condones whatever tickering it took to accomplish this.
I’m suspecting some kind of bug. I’m guessing the keyword search doesn’t handle all numeric keys very will. Damned shame. First bug ever in our software (unless it’s proven to be a feature).
