Ok im running this contest on my site where everyone can vote every 18 hours. I check using ip address and cookies to make sure the person hasnt voted within 18 hours.
Well I am sure this person is cheating. But I cant prove it. I accused the person the first day and they said they are from a small town and everyone has same internet provider. Well everyone in there town must asdl service then. I found out throught the asdl providers site that each time they log in they get a different ip address. Any suggestions on how to prove the person is cheating?
I got the following three ip addresses within ten minutes. with the xx.xx being the same everytime
I don't know the code off-hand for this, but you can probably collect more info about each user, like the browser version they are using, the screen resolution they are using, other little tidbits like that. If they all match up then you've probably got a cheater on your hands.
We had a similar issue one time- and we ended up racking our brains and came up with using cookies instead. They were a pain to put together, but it caught a lot of attempts by the same users- aka cheaters :) Good luck!
