Title.
I noticed that even though we can whitelist posts we upload by assigning an exclusion to a blacklisted tag (e.g. -user:myUsername), the same exclusions don't seem to work for favorites or subscriptions (e.g. adding -fav:username to a blacklisted tag does nothing at all).
We could just fix these exclusions, of course, but I figure since the favorites list is for something we like anyway, it could probably serve as a whitelist.
