Ove been thinking about this problem with Facebook's recommendations: While previous "dislikes" are taken into account when predicting of a user will interact with a post, the system is still fundementally trying to predict "click through rate" not whether the user enjoys a post or not. It might even be that disliking something is positively correlated with clicking it, since they may have watched the video before deciding it is no good.
