My understanding is no, you can't.
But if you think about it, that would be only fair. If you don't want them looking at your page, then you shouldn't be able to see theirs, either. Otherwise, it's not really a social networking tool, it's more voyeuristic.
Sorry, i don't mean that in a mean way, but I just had a friend on facebook be very upset, because a guy who had hurt her yrs ago had contacted her on facebook. She wanted to be able to see his page, and see what he was doing, what he was saying, if he was "friending" any of her friends, etc - but she (understandably) didn't want him seeing her page or anything. It was very frustrating, because if the relationship was that bad that she didn't want him seeing hers, she had no business wanting to look at his.
Good luck with whoever is blocking you / you want to block! :-)
