Just to emphasize two points already mentioned: the "spam filter" is an automatic thing: editors will hand=check everything caught there, just as they do anywhere else. It's not an automatic, or even a default, rejection.
And a lot of people are concerned about accidentally spamming the ODP submittal process. (Thanks!) But if you submit to the wrong category, discover your error, and then submit to the right category, we won't call that "spam". We'll call that "took two tries to figure out how to help us." It's not the same at all.
