Twitter users: Please use your twitter knowledge to help me out..I'm freaking out!!?

I see you've changed your "user name" since you asked all the many, many times before. It's becoming very annoying and you really need to find another way to amuse yourself.
Let me explain it, then hopefully you will understand and can stop asking.
If you don't have a twitter account, no one can know if you look at their account. They cannot track your ip address, they cannot track you through a "viewer" on the page. They cannot track you, period.
Even if you had a twitter account, other people don't know when or if you look at their page.
