In this answer, Shog9 posted a screenshot that had two curious rows in it.
Now, in the screenshot, they are empty. But what does get put there?
The real moderator UI has other fields there.
Or maybe it doesn't; I have a user script I use to put stuff there, so it might just cut off after "seen". I forget.
Anyway, I wasn't about to leave that portion of the real UI visible in the screenshot. Even though I was testing this on a sockpuppet, it's just a bad habit to get into - make a mistake like that with a real account & suddenly you've leaked someone's personal information onto the 'Net. That's pretty rude.
So when I post screenshots like this, I usually replace the bits that shouldn't be posted with something ridiculous. I could just blur them out, but I like to hope this helps catch folks' attention a bit more effectively, and perhaps also serves as a reminder to moderators that they're acting as stewards and should handle other people's profiles with care even when it doesn't seem particularly necessary.
