Surely this can be cheated just as easily as any internet poll. i.e. I can print off a copy of your petition have everyone at my workplace sign it saying "worthy out" and send it in, whether they support Norwich or not. The only way the petition can really work is an by way of an entry or exit poll - at least that way a significant majority of those going in or coming out are actually Norwich fans. I think you may have seriously undermined your petition.
