I'd imagine that they'd not only be hit for being of poor quality, but also because they contain so much duplicate content. What percentage of the directory submission people actually use unique text to describe their site? I'd guess maybe 5%, if that.
Back in the day, you *could* get a DMOZ submission approved just for being of good quality and being listed was very beneficial. Now-a-days, you're lucky to find a "good" directory without bias.
