Alright I need some help cracking this code, nothing malicious or nothing bad. But it's bugging me... Ok, here it is. If you go to Slickdeals and Make a Thread. You can Vote "Thumbs Up" or "Thumbs Down". So I logged in to my regular user name, posted my "freebie thread", and voted Thumbs Up. Seeing how other people were thumbing me down for no reason. I wanted to "Thumb Up" my Post... SO.. I created a username and registered, go back to my thread and bammo, says "You've already Voted". Normal, so I Change my IP address. And I clear all my browser history/cookies/cache etc. I even Clear my Flash Cookies. And I Register a New UserName. I go back to Slickdeals and it still says "You've Already Voted". HOW DOES IT KNOW!?! HOW!? I cleared everything! I've even changed my Ip address! and Flash Cookies! Someone Please HELP me on this!!
