yep. there are filters out there, db reffer ... refer url, check the resource center, you have different options on how to filter out addtions from onsite submissions, submitting from outside ... don't know, haven't gotten that far on what I'm doing but I wonder if these will still not help you someway or another.

alphabetizing your valadation links -- hmmm, sorry can't help on that. why? to make them look nice?

good luck
