Don't worry. We de-duplicate non-anonymous signatures automatically, and anonymous signatures within 24 hours (before personal data is deleted). For anonymous signatories beyond 24 hours, we cannot verify there are no duplicates, though there is one human who manually reads all signatures and will try hard to notice and correct any abuse of the system.
