I only know of 2 or 3 admin accounts and that's it. Now there's all these other ones that seem to be popping up out of nowhere as of late. I think we should know about everyone who is running the site and monitoring reported content.
There is no "public" list but you may see different admins around, the list @Jessicocoa gave is accurate. Some admins are more "visible" than others because we all have different roles such as moderation, user experience, content, site development, etc. so some of us are much more active than others. That's why there are only a few admins listed in the mod messages we send out because those are the admins mods should contact. And for those who are wondering, the GirsAskGuys user is a shared account all of us use at various times.
Referring to one of your comments here about that question some users saw posted yesterday, that was a test question that was meant to be posted on our QA website we use to test features. It was posted on the production site you see here by mistake and it is now removed.
I've never seen a list either but I agree they're all over the place. I usually follow them as I see them.
Like Applefan said there's - xHoneyxBeex - RedRain - menguc
But there's also - DiogoRibeiro - The new Mytake lady - Some old bald guy - Some guy who claims to have a cat but clearly doesn't since he's a jerk about it - And possibly the boss jerk who may be any of the male accounts
