As I was digging through the new users, I found users who were improperly tagged as General with adult avatars and banners. Following a chain of users with similar avatars, I found another user with the same, but they had marked their profile as 18+. I flagged the profile as I did the others, but had no idea that they were already marked until finding them in the pile of fresh users eventually.
Having a little icon somewhere on the profile page itself, unobtrusive to the rest of the page but there for confirmation purposes, would make mistakingly reporting profiles happen less, I feel.
