One of Judith Kostner aliases listed at
IAFD is Judith Bodor. However, Judith Bodor has her own profile as
Suzan which matches with her one at
EGAFD. Also, IAFD have a profile for a lady they've called
Jacqline but the profile pic looks like it's Judith. They have listed only two films for her, Buttman's Big Butt Euro Babes (see
here for more info) and the other is Empreinte du Vice under the name of Judit but she is probably this Judit on
EGAFD.
