The wiki on minigirl states the following:
Please note that dolls are not to be tagged with this as they are naturally supposed to be smaller than the average human character. This includes dolls which appear to be human, but are known to be dolls according to their respective copyrights.
...is that second part proper?
I thought that tagging was generally supposed to be based just on what you could see in the picture, not on details of the copyright -- if (for instance) someone draws a picture of a character that is usually a doll as a real tiny girl, it should get the minigirl tag, shouldn't it?
