in reply to Quick and easy way to prevent multiple votes?

Cookies wouldn't work well, as they could be deleted by a knowledgable user, who could then gain infinite votes. The way that many sites do it (perlmonks and slashdot, for instance), is by tracking IP. This has some margin of error because of things like proxies, and people voting from more than one IP, but is basically the best all-around way to do it.

    I've done both cookies and IPs in the past. Users coming in from dial-ups can always reconnect, delete the cookies and vote again, but that is such a pain in the 455 that I can't see someone doing it over and over and over. Even permanent IP users could spoof the address and do the same process, but that's even a worse case of nothing-better-to-do-with-ones-life.
