I'm not sure if rights is the correct term to use here. Those are choices made by the host, the experience they want to provide; and the members who have chosen to participate, accepting the terms of the host, aren't they? Well, I guess rights of some sort are involved, the commenter ceding copyright or some such to the host.

I'm not a lawyer, and admittedly haven't taken the time to look up the appropriate legal terms and other minutiae involved, rather relying on the kindness of my fellow commenters to extend to me the benefit of the doubt with respect to what I'm getting at, and helpfully clarify anything that needs to be. Thanks :)
