tube site submissions with backlink
 

I`m looking for a list of tube sites who accept submissions from ordinary users with a backlink but not like Partner Content Program.
I found these ones :
http://www.hardsextube.com
http://www.pornhost.com/ (has less traffic)
http://xhamster.com - doesn`t allow a backlink , but at the user`s profile it has a field with your URL.
