When you make a search on the Google site (for example), they store your IP address, cookie info and user agent string, correct?
I was just thinking the other day, why don't sites collect your User Account name? They would be able to perfect their advertising techniques even further if they could get the username and IP together.
Then I asked myself, were they possibly already doing this? Especially if I had something like Google Toolbar installed, could it have possibly been relaying my search queries to its servers with my user account name attatched to the searches/history etc?!?
Reason I ask is because I used to use my full name in the user account. I would hate the thought of having my full name attatched to some server logs somewhere with all my searches and history.
EDIT: When I say User Account, I mean the account you sign into your computer on, not your site specific usernames. For example, my admin account on Windows 10 is "kurt". Would sites like Google or YT know that?
