Firstly,

I don't see why you chaps are mentioning nofollow, the tag does not appear on any of the listings I've checked in dmoz.org

Secondly, where small directories have used nofollow, they're usually found out rather quickly,

Where the submitter is using submission software (a spammer to some people), it can take a while i guess before directories using nofollow can be weeded out of their submission lists
