I have just read these threads and feel obliged to make a comment firstly this appears to be a private matter but on a professional level i have to put my experience down.
Always seen Certs, never been abused but have done sub/Dom content share and they have always adhered to my wishes even when filming and never overstepped the mark. They have only ever done up to the limits i expressed.
I really hope you sort things out Gina xx
