“Tween” is 20+ and “child” is more like “looks below 12”?
Yeah, no (not to you).
If I understand this correctly then the suggestion to make the loli definition more ambiguous. That's not acceptable.
If someone wants to look at such images then there is also a petite tag, although it's not a tag that describes the character's "age" (unlike the loli tag).
