Lodging for breastmilk

An ad in Craiglist offers a swap of lodging for breastmilk – for all members of the house:

We are offering a free room for a woman who is willing to provide breast milk for consumption to the household. We are an otherwise vegan house but have recently read A.O. Wilson’s study of the benefits of human breast milk to all human beings of any age. This is not sexual. Neither appearance nor sexual preference are of any concern to us.
