i'm a little bit paranoid. i have a dynamic ip and change my ip after creating one youtube account. if you were as paranoid is i: is this enough or do i have to delete cookies after creating each account? i do the following: 1. create account 2. logout 3. change ip 4. go to youtube.com and create the next account. is this enough? would you delete cookies if you would use my paranoid technique? maybe changing ip is useless if i do not delete cookies?
