I just clicked on a link from another thread (www.muchosucko.com) and noticed the personal ads were supposedly for girls from my area. While I doubt any of the girls pictured were actually who they were said to be, it got me curious. How do they know where I'm from to target the ads toward me? Is it just from the IP address my provider is using or is it tracking cookies I've picked up somewhere? I run antivirus and antispyware software and am behind a firewall, but i'm wondering if I should do something more.
