I think that the changes only apply to figures that look under 18 years of age. If an image comes into question, it's up to the moderators/admins to determine if in their opinion the figure appears under that age and rule to either remove it or leave it. Personally I don't know what an 18 year old looks like. I see kids who are 10 and 12 being mistaken for being much older than they are. Girls are developing faster and wearing makeup, boys are taller, they dress in "adult" style clothing, their vocabulary is more grown up (if they don't speak in that stupid Dewd speak) . The only way to really know is by asking the parents.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
