I am getting originating urls in my user tracking like this /index.php?main_page=http://myloversplace.chat.ru/images? and /index.php?page=http://dwlz2.dwlz2.com/~dwlz2/ice.txt/ and other strange addresses, I have checked some of them and there is no such address. Where are these coming from....they always go to page not found.

Any ideas?
