Filter out the user's own uploads and favorites from their recommendations. Note that in most cases a user's top-N recommendations will be things they've already favorited. If a user has 10,000 favorites, most of their top 10,000 recommendations will be their own favorites, so we have to generate a little more than 10,000 recommendations to be sure they won't all be filtered out. In other words, the more favorites a user has, the more recommendations we have to generate. The upper bound is clamped to 50,000 for performance reasons. If a user has more favorites than this we may not be able to find any recommendations for them.
