People love to hate this directory and are doing everything they can to undermine it seems. There is a listing on eBay right now offered for sale by a seoblackhat of a PR5 category editorship that you can purchase for chump change. Apparently you get the login in and password details for the editor position with the auction and whisper not to say anything to DMOZ. Sounds like an SEO adventure. Worth it you ask? Probably not, but then again it could be for the right person.
Update: Appears that the auction was pulled and bidding is no longer available.
