It's not a secret, but to place as much emphasis on fear of personality voting as you do is, in my humble opinion, downright silly. If you want to ask a question you're not sure you should, tentatively use the chatterbox. The question will disappear in the next five minutes and even if an evil personality voter happened to be around and picked it up, you're not likely to lose a lot more than half a dozen of your precious XP.
