Difficult to say. Please note that - as informator said - we can't give legal advice in here. Only the AOL legal department could do so, and I dont think it's very likely you would get a response from them easily.
There was a related case quite some time ago, when someone asked if he could use the same description heused for an ODP site suggestion somewhere else. This was answered with "Yes". When suggesting an URL including Title/Description you don't give up your rights on the text. According to the ODP license statements, you just grant Netscape/AOL a nonexclusive license to use the text you suggested.
But that doesn't help you much, because you can't know if the submitter wrote the description himself or it was written by an editor...
I don't think a few of those are much of a problem, but that is just my personal oppinion.
