Hello. Currently, I run a voting site where voters are tracked by their IP address and can only vote once every 12 hours.
The system works well, except it can be exploited very easily. Visitor's only need to renew their ip to be allowed to vote again.
I have captcha in place to prevent bots from doing this, but if someone were dedicated, they could get a lot of free votes.
Does anyone have a better way to track such things? Cookies will not work either. It's easier to get around than an IP. Perhaps I'll have to use a language other than PHP?
Thanks
