I recently submitted a question to unix.stackexchange, and the next day (after it had been answered) a moderator came along and "improved" the layout of my question. Objectively the result was no worse than my original, and perhaps it was indeed better, but I can't help feeling like my private space was violated by that.
Your questions and answers aren't really "yours" on SE. That's the way it works. A bit unusual, but nothing wrong per se. Like Wikipedia, but that you still get credit for what you started.
Tome, I've had the same thing happen, but I chalk it up to simply the way the site works, which I knew upfront. Occasionally, however, the "help" in refining my question isn't that helpful...
