There is no foolproof way to prevent vote rigging, even if you require voters to be registered with authenticated email addresses. There are more subtle ways to catch cheaters but anyone with general savvy in the workings of web applications can easily circumvent them.

The most you can do with the logged information is to analyze the voting and traffic patterns and filter out suspicious votes. Correlating IP addresses may help, but only to some extent. There is also no way to conclusively prove that voters who share the same IP address (or subnet) are the same person, or that voters with different IP addresses are different people, unless you obtain evidence from their ISPs (good luck with that).

On the other hand, Quentin could just as easily withhold all voting information, and everyone would be none the wiser.
