If a user serially downvotes someone so much that they use up all of their votes for the day, earning the Suffrage badge, will the daily anti-serial-downvoting mechanism revoke the badge?
If it won't, I'm of the opinion that it should. Badges are for positive behaviour only, and they shouldn't be a reminder of past bad behaviour.
Update: The anti-serial downvoting has revoked the downvotes of the user in question, but he still has the Suffrage badge.
