Looking at patterns in the IP addresses of voters you can figure this out, as all the IP addresses in a private network/dial up will have many of the same numbers in them. I assume GameFAQs can do this in some fashion because this is why I was supposedly DQed in 2007. Also I think GameFAQs collects more information than just IP address when you vote-- if you collect information on the browser used/OS/etc you can usually catch a private network because they'll usually have a standardized setup so everything will match up there.
(I didn't cheat back then, mind you, but I did often vote on a dial up connection so I figure that's why I was "caught"-- only takes a few other regular voters using the same dial up ISP to make it "fishy"-- though I'm sure if they actually analyzed the actual content of the multiple votes and didn't find any real pattern in the "stuffed votes" favoring one side I would've been cleared there-- but Bacon is stubborn and would have none of it)

No problem!
