No, because each browser stores their own cookies, and cookies can be deleted. A user would be allowed to give as many votes, at minimum, as the amount of browsers installed on their computer. If they figure out to delete the cookies they'll get unlimited votes.

I don't think someone would do that to vote many times. I think php restrictions are not more secure, users can restart the rooter, get new IP and revote.

 

But my users are mostly anonymous, so can there be a cookie restriction for them?
