A service that promises to tell who are the 200 most recent visitors to your Twitter account, TwitViewer could be a phishing scam. Just registered through an Arizona proxy server today, using the service is totally free, but there’s a catch.

You need to give these guys your username and password in order to a photo-gallery-like display of your last stalkers. In return, TwitViewer will user your account to automatically send the “Want to know whos stalking you on twitter!?: http://TwitViewer.net.” message to all your buddies without permission.
