That's different because it's an end-user action, not an internal action. I always know that the person who is saying that they're a Navy SEAL may not be or that it might be Morgan Freeman's or President Obama's PR person answering the questions. It's a lot different when the site admins use their root privileges to put words in people's mouths. Imagine if someone edited your comment or my comment to include a bunch of racist or hateful comments.
