>If I don't know whether my website has or has not been reviewed, then at what point should I consider resubmitting?
>Given the absence of any information, I have to believe that the process of serial review of submissions is a misnomer and that sites are reviewed on a random basis.
This is absolutely correct. There is simply no way of reviewing submittals serially even if an editor were insane enough to want to. Even within a category, I review in a random order.
And this concept is so obvious, I'm amazed that ... you're the first submitter to figure it out.
>If that is the case, then a simple numbers game with multiple postings should warrant increased probability for success with a DMOZ listing given the increased probability of a random listing review/posting 'hit'!
But here you fall off the truck.
The numbers game works, but not the way you imagine.
If you repeatedly submit to one category, the software automatically deletes the duplicates....wasting your time but not ours. And that's OK with us if it's OK with you.
But if you repeatedly submit to DIFFERENT categories, then ... editors don't REVIEW those submittals, they merely move them to the right category for review. For awhile. Pretty quickly they notice you're doing what is called "shotgun spamming". And then you've got a reputation as a rude spammer, and your site enters the "whack-a-mole" zone, where editors try to quickly nuke all but one of the heads.
The emphasis is on "quickly deal with rude spammer", as opposed to "make sure we don't lose a single precious submittal".
And the result is, there's a MUCH higher chance of ALL submittals of that site being accidentally deleted -- or indeed of all submittals related in any way to you being systematically deleted.
By the numbers, the best bet is to submit twice, IMO about six months apart, and before the second submittal to look very very carefully at whether the first submittal was to the right category.
And, you know, that's consistent with the submittal policy, and pretty close to what it explicitly and specifically says.
