A question about my myLot referral link

Tweet

I placed my referral link on a message board I frequent. I was testing the link to see what happens. When I click the link I am taken to my own myLot home page with my username and password populated. Obviously if someone clicks on the my referral link that can easily sign onto my account. Is this because I myself and signed on automatically because it's my computer? Does whoever click on the link from another computer see my info or do they see a generic sign on page?
