The proper way to get a site into the ODP heap, with the hopes to get it reviewed and listed is to manually choose the correct category and suggest the site using the suggest URL link. It is only by manual submission that a category can be correctly selected, it is only by manually writing up a description and title that you can increase the chances of catching the eye of an editor.

How to suggest a site to the Open Directory specifically states Auto-submission software is (and always has been) a violation of this procedure. Sites submitted automatically are flagged and deleted after the submission is accepted, without notification to you

Auto-submission software and/or site submission services are generally inexpensive options that allow you to submit your site to twenty search engines, to even to 247,589 search engines. We can wonder why anyone would believe there are that many places to submit, and can question whether these services offer any value for the money, but for the most part, a service that submits your site to Google or Yahoo is not going to do your site any harm.

However SEO services that submit your site to DMOZ, can cause great problems. Many of those who offer submission services are clueless, and will use shotgun approaches. Not only will the site go the wrong category, it may well be submitted on a monthly basis, or to multiple categories. There are several SEO sites that continue to suggest that repetitive submission is required until your site is listed.

Most of these submission services (or programs) simply take your URL and throw it at all known search engines together with a canned description. For the price they charge, good luck at any quality. Be thankfull if they even get you correct spellings.

Heed the warning on the DMOZ submit page, auto-submission of sites can result in banning and blocking of your site.
