I'm trying to register multiple accounts in a website I prefer not to mention. The rule is 1 account per pc but this is a blackhat forum, right?! well... before registering my second account I used a proxy to changed my IP, I deleted cache, and temporal files, and I even changed browsers, and when I went to create a new account it gave me a message saying I already had an account with this computer! what the heck!! The registration process only requires my name, and email, and nothing else. No installation, nothing! how can it detect I'm using the same computer after deleting and changing all that info? Is is possible to get pass that thing? Thanks in advance!
