It's important to recognize that not everyone is going to appeal to everyone else's taste. With that in mind, I would suggest implementing an option to hide or dislike certain models so that any movies they are a part of won't continue to appear in the user videos list.
Ideally, it should be possible to dislike them from a playing video context.
Edit: appears that this option is available on the desktop. It would be great to have it in SLR app too.
