Let's look at this from a practical point of view.
Pretend you submit a site and I make hte decision that it is not listable.
What do I tell you?
Sorry, your site is not litable.
If I do that, then the immidate and obvious reaction you will have is to send back an e-mail saying: Why?
OK, so I tell you that it had too many broken links.
So you fix the broken links and immediately send me an e-mail insisting that I immediately re-review it. I tell you to resubmit, you get mad because you have already waited a year and don't want to wait again.
OK, you resubmit and some time passes and I happen to look at your site again. Now I discover that there is something else wrong, so I decline to list it and send an e-mail.
You get mad and ask why didn't I tell you that the first time? The answer is that I didn't get that far. Once I hit a spot that makes a site unlistable, I stop reviewing. After all, I am not in the site refiewing business, I am trying to judge the suitability of a given URL for our directory. You don't care about any of that, you just want your sitge listed.
This same thing could playout two or three more times, and you site could, potentially never get listed, and come away feeling like we have been jerking you around.

If you are a spammer hoping to suck the life out of the ODP, the minute you get the notice from me it tells you several things: how long it took me to get to attempt #17. That the technique used in attempt #17 did not work that it is now time to try attemet #25 which is a variation on the technique used in attempt #17.
