I visit a streaming site, www.younow.com, and it's somehow identifying who I am just from the browser. I had to recreate an account there because of some unwanted attention but as soon as I recreate an account(via google+ login so not registered on the actual site)the site knows who I am and bans me because multiple accounts are not allowed. I use distinctively different information so I'm sure someone noticing me is not the case. I have also tried changing my ip address, my mac address, clearing cookies and cache but the same thing happens. However, when I create an account on a different browser I have no problem at all but when I log-in in that same account through Firefox it somehow gets 'tagged' again and the account gets deleted instantly. How am I being identified when there are no cookies before visiting the site?
