It may be accepted in contemporary language, but it seems to be confusing (not only for me as it appears).
Who = nominative. As I don't have any context and nouns are not declined in English "Who does the woman love" sounds like an awkward form of "who likes the woman". At least for me as a non native English speaker.
I've compared a few usage ratios of subject and object pronouns and got these results:
- them : they -> 1 : 2.7
- him : he -> 1 : 3.8
If whom were the only acceptable objective case form of who, we would get a similar result, but:
- whom : who -> 1 : 30.1
Which is a clear indication of the fact that who is very commonly used as an object pronoun.
By the way, "whom" is accepted as well.
