Honestly, I think rules should cover ever edge case that you can brainstorm within 10 minutes of thought. If some unaffiliated party can come up with the edge case easily, your rule should have a guideline about it--even if said guideline is only internal documentation. To be fair, were I running this moderation system, I would simply say anything unclear would be dealt with on a case by case basis, and those decisions would set precedent like in the actual legal system.
