Ther is probably nothing that you can do. Any submission of other than the root URL is technically spam.
The editors will clean out the spam, and hopefully at least one of the submissions will get send to the correct category -- but therte are no guarantees. Usually, until such time a sa history of spamming is identified, editors will do the right thing and try to move the root URL. We don't extend any such courtesty to established spammers.
So your best bet, assuming that you have not massively spammed the directory. is to just hang tight. If, after a long period of time, perhaps a year, you have not seen your root URL appear in teh appropriate category, you could take a risk and resubmit it once, but definitely not more than that.
Hope this helps.
