Serial upvoting of a single user's questions I have little doubt are detectable and reversed...
But what about dumping the daily allotment of 40 votes in a short amount of time on many questions from many users, a method that I should add, can earn someone 4 different participation badges (including a gold one).
Why isn't there flood protection on voting, just like on commenting? Are those voting related badges helpful (Suffrage, Vox Populi, Civic Duty, Electorate) in the way they are currently designed?
