Isn't there some kind of rule against having pics of women with boobs bigger than their heads?

The rule is against absurdly large breasts and since Mai is known for having very large breasts, i think that the size on this picture isn't absurd at all.

Sagging does not increase the size of the breast compared to the head.

Is there really such a rule ??
