How confident can we be in the Fraud Bot's ability to sniff out fraudulent votes? Is there a margin of error?
I've inspected the cookies that get set, and don't think that by themselves there is enough data. Especially if someone is clearing their cookies every time. Now, if you are tracking their IP, timezone, frequency patterns and date/time of votes, (or some other set of super secret variables), that might be enough to computationally determine fraudulent votes.
