Getting rid of iphone.iusethis.com - private beta Login Window?

Hi, since a few days ago, each time I open a new page on iusethis.com, I'm getting a login window for iphone.iusethis.com private beta login.

I don't own an iPhone (yet ;) ), and my normal iusethis account login/password doesn't seem to work either.

Is there any way to circumvent this login window?
