A new site www[dot]youare-blocked[dot]net was created ~9 days ago. It asks for your hotmail username and password with the idea of telling you who has blocked you. Searching for the site only shows a few people have entered their details and received an under maintenance page.
From the sounds of the site, it’s just farming hotmail accounts for reasons only the site owner uses. If you get an email with a link to this site, don’t follow it. If you already have, change your password now and then change the password to any sites such as ebay where you use the the same password.
