I am using the component to a survey in 5 days totaled 26,000 votes. Everything works perfectly. I set the vote every 24 hours with IP and cookies, but I did not use the user registration information to speed up the voting. Unfortunately, the new browsers have the "browsing secret" and so site visitors vote on all the time.
We can lock the navigation secret?

I hope I explained myself well, sorry for my english
