probem with expired web 2s

Hey there.

I have some problem with expired tumblr and weebly accounts. For example, 400 addresses which were found today, most of them without PR. All of the server’s response 404,Vanity Name – avaliable. http://joxi.ru/J2bNZq4S8xpZ26 . None of the 400 is not available for registration .
This is part of the “free” address :
