If it is eligible for listing, then it will eventually be listed. Resubmitting again while it is waiting means it is now tagged as a recent submission, not as one that has been waiting for a long time. That doesn't help you or the editors, especially an editor who decides to go and process "old" submissions first.

If it has already been rejected as unlistable, then editors don't ever want to have to review it again. That is, unless the site is radically different (better!) in scope and content, and a long time (like more than a year) has passed since the last review. If you keep resubmitting it at short intervals, then you will soon gain a reputation as a "pest" and all your future stuff is then dumped without being considered at all. This works the same way that this forum treats a new poster that posts several spams in a row.

If it has actually been reviewed and is already listed, then do not submit again. You are very likely not going to get any additional listings. In general, don't even try. However, if there is a gross error in the description of the site you might want to submit an update request. If that request is just to get more keywords in the entry then it will certainly be rejected.

Editors set up a forum, and for 3 years tried telling webmasters some information about their listings. After more than 30 000 attempts the plug was pulled. This was because it was realised there is nothing that editors can tell a reputable submitter that could help their site be listed any quicker, but there is plenty of information that a spammer would like to know in order to be able to try spam the ODP better next time.
