Yeah, I noticed that. That's why it's at the end of the list, next to the obviously-not-serious icon. I was hesitant to add it, but it's pretty much a completely blank account and it was on most of the other icon collections already anyway.
I dunno. I suppose there are enough Fluttershy accounts now that nobody would miss it if I removed it. But then again, I don't think it's really hurting anything.
I'm making my own list and I've seen a few icons on your list and other lists that are a little fishy. Only because they're older accounts, (beebono is over 3 years old) and a couple others have actually changed their icons. I'm asking around if they are actual PLZ accounts or not.
I think it's because no one realizes that these accounts aren't plz accounts and they add them when deviants give them to the list builders.
