the creator of the avatar you are trying to get can blacklist themself so that no one can download their content via ripperstore, you are completely unable to get their avatars from the ripperstore website
You likely cannot find another website with the same avatar ripping functions. The best you can do is to find the original assets used to build the avatar, or find a similar model on ripperstore.
All anonfiles links are dead; long live anonfiles.
All, if not, most of them have been backed up to my Terabox: https://terabox.com/s/1okc55Iw4joYkYNjyplK1CQ
I will not be reuploading anything to other drives for a while, sorry!
