Prevent Manipulation of views by single user

Is there a way to prevent WPP from registering multiple posts views from the same user within 24 hours? Only counting one view on a post (per 24 hours/IP)? Currently users can refresh the page continually and send their post to the top of the leaderboard. The Data Caching temporary helps “trick” users into thinking their refreshes are not counting towards a higher ranking, but the views are still being counted and reflect once that caching period expires. Users frequently visit their own posts so we wouldn’t want to count duplicate views or those trying to manipulate.

Thanks for your time.
