Pattern voting

Selecting contest options across multiple contests in a predetermined pattern intending to signal one’s identity to someone else. The possibility of pattern voting can be an issue for publishing Cast Vote Records (CVR) because it may compromise voter privacy if there are enough selections in each published CVR to make it likely a selection pattern might be unique.
