We detached this subthread from https://news.ycombinator.com/item?id=13038244 and marked it off-topic.
I can think of a single example where we edited a user's comment without them asking us to, and it happened a few days ago: https://news.ycombinator.com/item?id=13012176. As you can see, I posted what we did and why. The alternative would have been to kill the comment outright.
