So all names were just changed to include last names so that we don't have 5 different Sakura's under 1 tag, but games aren't differenciated out? Nice.
Tags are not guarenteed to be proper. Anyone can edit them. Someone threw happiness up on a bunch of my majo2 pics (They were indeed quite happy).
For that matter, not all characters have had their names changed. There's a number of posts from majo2 that don't have full names. (I bring up these examples simply because they're tags I'm familiar with).
